I have long wanted to make such a device for myself, since it is impossible to properly tighten the band clamp by hand, and then over time, grease will fly out of there or it will fly off. And finally I found the time, and in the garage, as they say, I assembled a useful tool from “shit and sticks.”
We will need: 1. Metal tape 2-3mm thick. 2. Old stabilizer link 3. Two nuts or brackets for the diameter of the stabilizer link. 4. Grinder with different circles 5. Welding
Installing a clamp allows you to avoid leakage of the embedded lubricant. During operation, the CV joint clamp may become loose and debris trapped under the boot will soon cause a crunch and the need to repair the joint, so at the first release of lubricant, measures should be taken to prevent depressurization.
Do-it-yourself clamp for tape clamps
The final stage of CV joint maintenance or replacement is the installation of a band clamp on the rubber boot. The problem is that it is impossible to tighten it by hand with sufficient force. As a result, many people simply buy worm-drive clamps for screwdrivers separately and throw away the standard ones. If you make a clamp of this design, you will be able to tighten the band clamps very securely and quickly.
Clamp manufacturing process
To make a clamp, you will need a section of profile pipe 12-15 cm long. A hole with a diameter of 8 mm is drilled in it 5 cm from the edge.
Now you need to cut the bolt to screw on the clamp. When using a 15x15 mm profile pipe, it is enough to leave on it a piece of rod with or without thread 20 mm long (excluding the head). Then it needs to be sawn lengthwise. The slot must be thin, so it should be made with a 1 mm disk or a hand hacksaw for metal.
Now you should cut off the walls of the tubes from the side of the hole, as done in the photo. The remaining burrs from the grinder are removed.
To use the clamp, you need to install the clamp and manually tighten it. Next, you should insert its edge into the slot of the bolt inserted into the hole in the clamp.
Holding the device with one hand, you need to rotate the bolt with a key or head, thereby winding the tape onto it.
The tape will bend and everything will hold together.
Then the bolt is removed and the clamp tube is removed.
Homemade clamp for plastic ties
To make this homemade clamp, you will need a hex head bolt. It is necessary to make a longitudinal cut in the body of the bolt using a grinder.
We weld a piece of round steel rod to the bolt head. Screw the nut onto the bolt.
The author makes the second part of the clamp from a metal strip. You can see what this part looks like in the photo below.
Making such a thing is very simple. We cut off a piece of the strip, make cuts with a grinder and bend the edges on both sides in different directions. We leave a persistent “finger” on one side.
After this, we connect both parts of the homemade product together, and the clamp for plastic ties is ready. Now let's look at how to tighten the clamp using this tool.
The principle of operation of the device is quite simple. First, we make a loop from a plastic tie. We put it, for example, on a hose that needs to be tightened. We insert the end of the tie into the slot in the bolt.
We rest the persistent “finger” against the tie lock. And after that we begin to twist the bolt - at this very time the tie will be tightened.
When the plastic tie is completely tightened, we bite off the excess part with wire cutters.
You can view the step-by-step instructions for making a homemade clamp for plastic ties in the video below. The author of the YouTube channel bricolage du cardan shared this idea with us.
In this article, we told you about three types of homemade clamps, explained how to make them and showed the principle of operation. We hope that this information will be useful and will help you make a clamp with your own hands.

A simple tool for tightening automotive strap clamps
Greetings to everyone who loves to make things and learn new things. Today we propose to get acquainted with an interesting device offered by the author of the TEXaS TV channel, namely, a device for tightening tape clamps.
Band clamps are usually used as clamps for the CV joint boot, steering rack boot, and also for tightening various automotive pipes.
The device in question is designed to facilitate and simplify the tightening procedure, as well as ensure a more reliable fit of the clamps. This homemade product can be useful to all car enthusiasts who repair their iron “horses” on their own.
To create this device, the author needed:
1) A piece of metal (metal 2.5 mm thick is used here); 2) Two nuts (in this case the author uses 8 nuts, with a 13 wrench). 3) Old stabilizer link. 4) Bulgarian. 5) Drill.
According to the author, it will take approximately 1 hour to create this device.
So, here's what you need to do with all the above parts to get a useful and convenient device for tightening car clamps.
A strip 23 mm wide is cut out of metal. However, the dimensions of length and width are not of great importance here; they were chosen arbitrarily by the author. Accordingly, you can make such a strip larger or smaller - the main thing is that the device is convenient to use later. Next, a wedge-shaped narrowing is made at one end of the strip. A metal ring is welded to the other end - for ease of storage - from the stabilizer strut.
At the next stage, two nuts are welded to the strip - at the place where it begins to narrow - through the internal holes of which the rod will subsequently have to pass.
Therefore, if these holes are smaller than the diameter of the rod, as happened when the author created the idea, they will have to be expanded to a suitable size.
We take the old stabilizer link and now cut off such a fragment from it with a rod length of 35 mm.
Carefully make a through cut in the rod using a grinder (we will tuck the tip of the clamp into it).
Insert the rod into the holes of the nuts.
On this, in fact, the creation of a homemade product is completed. Our clamp tightening device is ready to use.
It works very simply. We put the clamp on the part that needs to be equipped with a boot.
Then we put on the boot itself, making sure that it fits into its seat.
After this, we put the clamp on the boot and first tighten it by hand as much as possible.
And now it’s our turn to adapt. We attach it to the clamp and thread the tip of the clamp into the cut of the rod.
Now all that remains is to turn the rod a few times, and the clamp will tighten without much effort.
After we have clamped the clamp, we turn its tip up, secure it and cut off the unnecessary length.
By the way, this homemade product is easily simplified. So, if you do not have welding skills or simply do not have a welding machine at hand, as well as an unnecessary stabilizer bar, this is not a problem at all.
Design features of the product
A clamp is a simple and effective device that has a lot of standard variations, but, in essence, they all have similar design characteristics. The difference is presented in the form of shapes and fastening devices. Their use is most common in the field of installation and repair of pipeline systems; this determines another characteristic feature of the design. For better fixation and tightness, the product often has a rubber gasket.
Regarding the practical benefits of the products in question, we can say that without them it is almost impossible to carry out high-quality fixation of the pipeline, both horizontal and vertical.
The line of types of this device begins with the simplest one-sided products, which are a threaded pin. It then continues with variations that differ not only in the greater complexity of the design, but also in size (this should be understood as the maximum diameter of the pipe for which a particular product can be used) and intended purpose.
Clamps
The most common problems that clamps help solve:
- Repairing cracks in pipeline systems. Depending on the type of product, even fairly large damage can be covered.
- Pipe fracture is not a common but serious problem. For the most part, it is encountered by those who professionally install and repair pipelines.
- Also, if it is necessary to eliminate “fistulas” in water pipes, clamps are again widely used. In such a situation, it is necessary to use a soft substrate.
Note! If the pipe being repaired is used to transport corrosive liquids, then it is necessary to use a type of fastener that can withstand these specific operating conditions.
- Specifically for steel pipes, the product can help reduce the risk of leaks caused by corrosion. Situations often arise where it damages the metal so much that a leak can occur at any minute.
The market is saturated with all sorts of configurations of clamps from different manufacturers. Factory production, in addition to professional manufacturing, also provides a guarantee of quality. After all, the products are manufactured in accordance with GOST. Such government quality regulation is associated with the high degree of role of clamps in maintaining the integrity of the structures in which they are used. Based on this, the question arises whether it is worth making a clamp for a steel pipe with your own hands.
Homemade pliers for CV joint clamps. (Oetiker stainless steel clamps)
R.Petrovich
Master Advisor
I made a device for mounting clamps; I think this tool can handle even the toughest stainless steel clamps. Anyone who has a welding machine and an angle grinder can make such a device. The main working parts are made of two cutters, I don’t understand cutters, I found cutters made of some strong alloy on the market, they are without soldering, a file does not take them, the cross-section of the cutters is 10*10mm. The cutters are probably hardened and fragile, to be on the safe side, I released them on the gas stove; after the release, the file began to leave faint marks. I formed the working parts in the cutter with a grinder with a small thin circle, the metal is quite hard and reluctant to give in. After the cutouts were ready, I connected the halves and fastened them with several welding points, and in the connected state I ground down the working parts to a thickness of about 1.5 mm. It was decided to weld the cutters into the handles of the pliers; I just happened to have some unclaimed pliers lying around, and this was the result.
The jaws will be tightened with an M10 bolt through a long nut; the nut is welded onto two plates. You can take a regular bolt; due to the long nut, the load on the thread is small, but a ball with a diameter of about 6 mm must be installed in the end of the bolt to minimize the friction of the bolt on the cutter. Here's a photo of what happened
Included with the GKN plastic boots are Oetiker clamps with a section of 10*0.8 small and 10*1mm large, for which the tightening torque is 5000N and 7000N, respectively.
Let's calculate the twisting force, the lever can be neglected, and the friction of the ball on the cutter.
Мр is the torque required to create an axial force on the bolt. Мр=0.5*F0*dср*tg(xi+po) xi=atg(P/(Pi*dср)) FO - axial force of the bolt dср - average thread diameter. xi is the thread lifting angle. P - thread pitch ro - friction angle of the threaded pair po=atg(fp), fp=0.15 - friction coefficient of ungreased bolt-nut

How to make a wire clamp - step by step diagram
Step 1: Measure the required wire length
First of all, let's cut off as many wires as the diameter of our connection requires. We don’t need measuring instruments, just wrap the edge of the wire around the pipe and estimate the ends for twisting by eye, usually 50-60 millimeters is enough. Then fold the wire in half and use pliers to bite off the excess. We bring the ends together so that they are on the same level.
Step 2: Correct clamp arrangement
Now that you have a wire bent in half in your hands, you need to make the correct “eye” at the bend, and the diameter of the “ear” should coincide with the screwdriver, which should fit freely into it. To maintain this size, just straighten the ends, insert a screwdriver between them and bring them together again. Of course, a Phillips screwdriver is best suited for such purposes; it is even along its entire length and does not have an extension, unlike a flat one. Next, you need to bend the resulting “ear” to the side, relative to the length of the wire, it will serve as a lock.
Step 3: Detailed installation of a homemade clamp
You’ve just made a wire clamp with your own hands, it’s okay if it looks unsightly, the main thing is that it performs its functions efficiently. All that remains is to install it in its place of honor and twist it tightly. To do this, bend it around the pipe, always in the form in which it is, namely twice, and cross the ends together. Then we insert a screwdriver into the “ear”, hook the other end and turn it clockwise several times until a tight connection appears. Remember that when clamping you should not be too zealous, you should feel when to stop so that the wire does not break. If the ends of the newly installed clamp are too long, we recommend cutting them off with wire cutters.
It is possible that the first time you will not be able to install a wire clamp made by yourself, perhaps you will not get the twist, or you will overtighten it, but do not despair, repeat the procedure for making the fastener again. We are confident that after several attempts you will get a high-quality and tight connection, and this simple technology will always help you out in difficult times. Patience and a little effort! But still, for the future, keep several clamps of different diameters in your household, they will definitely come in handy!
Making a clamp
First, you need to remove the latch itself from the body.
The recesses for the latch handle had to be slightly bored to fit the diameter of the latch. I made such a crank from a latch. I cut a longitudinal groove on top of the body (along which the latch handle moved) right through; before doing this, the mounting holes in the body must be welded or riveted, otherwise the body will fall apart.
One end of the body needs to be lightly ground onto a wedge from the planes below and above.
The second end was ground onto the wedge from the sides. In the middle of the resulting wedge, I sawed a small groove along the plane. The device is ready for use. Cleaned with a cord brush.
I decided to write a short article about the clamps that secure the CV joint boots in place. Since the ATV is used in mud, it is very important to monitor the condition of the anthers themselves, and of course, to ensure that they are securely fixed and prevent swamp-clay slurry from getting into the assembly.
I came across three suitable clamps, two of them came with anthers, the third I just bought in a store for comparison. And of course, each clamp has its own tool for work.
The most convenient and reliable clamp is the standard one. Firstly, it fastens as tightly as possible, and secondly, it is reusable, and if it is not specially broken in some way, it can withstand many removals and installations.
Spring clamps.
This type is used on objects undergoing linear expansion, when, due to temperature fluctuations, the system contracts and expands. Withstands temperature fluctuations from -40 to +200 degrees Celsius.
The simple design of such a clamp: a solid spring steel strip with two curved ends for hooking. However, they provide very strong fixation and sealing of hoses and pipes. It is very simple to secure such a clamp: you need to bring the bent ends together using pliers, put it on the hose and release it. The steel will spring back and take on the required diameter. A large range of diameters (10 – 60 mm) will allow you to choose the one you need.

How to tighten the CV joint boot clamp? 3 ways
Some newbie car enthusiasts are interested in the question: how to tighten the CV joint boot clamp yourself so that it holds securely? Options arise: is it possible to use plastic clamps instead of metal clamps? They find out, can this be done with wire? Are you wondering if it is possible to install helical clamps on CV joint boots? Immediately about plastic: plastic can be soft or fragile, in general - not reliable! To be honest, in practice I have never seen these spare parts or the drive fitted with plastic clamps. Regarding the wire:
this action is the invention of the wooden bicycle, in my opinion.
This method can only be used for a temporary delay. But in the nature of car enthusiasts, as we know: there is nothing more permanent than temporary. In addition, choosing the appropriate wire so that it does not cut the boot itself and is not too soft at the same time is a rather savvy task. And when using helical (worm-shaped) clamps, there is a high probability of the screw itself unwinding or clinging to something while driving. How to tighten the CV joint boot clamp?
So, we use special clamps designed for these purposes. They come in two types. The first one is with a U-shaped lock. The second is of the tape type. Both types, as a rule, are made (even handicraft, “cooperative” production) from fairly correctly selected alloys. That is, they provide both sufficient rigidity during operation and the possibility of plastic deformation during the tightening process. In addition, both types are universal. There are only two main sizes, allowing you to fix anthers from 18 to 110 mm. in diameter. Let's take a closer look at how to use both options.
Band clamp (manual method)
The tape is quite easy to install on the boot using simple improvised means. Let's use pliers. So: we put on the clamp, pull the tip with maximum force with pliers, and bend it up. By bending the special antennae located on the clamp ring, we fix the end of the tape. We cut off the excess tape (bite it off with tongs or wire cutters - whatever you have at hand). Probably everyone can do this procedure, even a beginner.
Alternative options
You can also secure the CV joint boot clamp using a screw clamp. You can use a wrench or a screwdriver to tighten it. It practically does not require any skills to fix it, but it has a number of disadvantages that do not allow it to occupy the niche of clamps for CV joints:
- the grenade is susceptible to parasitic vibrations, which causes the bolt to unwind, especially if the clamp is installed without sufficient tightening;
- the design feature in the form of a protruding lock is capable of clinging during operation;
- frequent cases of loose fixation due to poor quality of clamps.
A temporary alternative placed on the CV joint can be a screw clamp with a key. Its installation can be done on the road to ensure that the lubricant is not contaminated when traveling to a service station.
When choosing between a band clamp and a clamp clamp, you should be guided by your preferences and the manufacturer’s recommendations. They both can last a long time if installed correctly. Care and accuracy when installing any of the fasteners will allow the lubricant to remain clean for a long time.
CV joint boot clamp, pliers, pliers and other devices and tools for installation, crimping and tightening of tape and plastic types
A homemade device for tightening tape clamps CV joint, RACK, PIPE, etc. Made literally in 1 hour of free time. You can watch the device in action in the video.
Clamp fastener
Some European-made cars have switched to using clamp clamps, as they combine reliability and simplicity. To install them, special pliers for CV joint clamps are used.
Placing the clamp on the CV joint occurs in the following order:
- The required diameter is selected;
- The clamp is located on the boot. It should be installed without distortions;
- To perform crimping, clamp pliers are used. If they are unavailable, you can use pliers of a suitable size;
- Upon completion of work, you should check the reliability of fixation of the clamp.
The main advantage of clamping fasteners is that there is no need to purchase expensive special tools. Carrying out the work with conventional pliers will ensure high reliability and long service life.
Power clamps.
These are high-strength clamps designed for use in aggressive environmental conditions: strong vibration, temperature and pressure changes, high humidity. They are resistant to corrosion and strong mechanical stress. Produced in accordance with GOST 28191 and DIN 3017.
When using them, the tightening pressure is evenly distributed throughout the clamp, which guarantees the strength of the fixation. And the high breaking moment makes it possible to resist strong mechanical loads.
Produced in different diameters (from 19 to 140 mm) from:
- of stainless steel
- galvanized steel
- brass
Power single-bolt clamps for the intake system.
Using special devices when installing a band clamp
To simplify tightening the tape and improve the quality of fixation of the boot, a special tightening machine is used. Its design includes:
To use the device, you should follow the plan:
- Place the tape over the boot;
- Insert its end into the cut of the holder;
- Place the holder against the clamp lock;
- Using rotational movements, begin to wind the tape onto the tool;
- With sufficient tension, bend the tape;
- Check the fastened clamp for correct installation.
To ensure high-quality installation, the final force must be correctly determined. The tightening force should not allow the grease to come out, but it should not allow the boot to cut.
Worm Clamps:
These clamps have a special screw with a worm thread. The rotation of such a screw leads to tightening of the tape. The tape contains through or non-through, pressed, notches at a certain equal distance. The type of notch determines the strength of the clamp. Thus, clamps with through notches or pressed inwards are less durable, and when tightened they can damage the rubber of the hose. The most durable and effective worm-drive clamps are those with a smooth inner surface of the belt and pressed outward notches. The screw head is specially made with slots for a slotted and (or) Phillips screwdriver, which allows it to be used even in the most difficult to reach places. Worm gears are produced in accordance with GOST 28191 and DIN 3017.
An important nuance: when choosing a worm-drive clamp, pay attention that the lower band of the clamp is welded to the screw mechanism. Clamps with unwelded tape, if handled carelessly, may unexpectedly open up.
These clamps are made from:
- galvanized steel – used at low humidity.
- stainless steel – suitable for use in aggressive environmental conditions, high humidity (even under water).

Pliers for CV joint clamps
Returning to the topic of replacing CV joint covers. Today's covers are tougher than the rubber ones of old. And it is almost difficult or impossible to tighten them normally with the usual tape clamps. Therefore, more modern clamps are used. They come in different types: with tricky locks, etc. But among inexpensive options, clamps with U-shaped “ears” are popular:
In my case it was exactly like that. And I decided to get some pliers to tighten them. In my case it is Licota ATC-2190:
The master came up with a tool - a clamp for tightening tape clamps
Often, screw clamps are not suitable for repairs, for example for a car CV joint. To tighten tape clamps, the master created a device that in many cases turns out to be more practical, and sometimes even safer, than store-bought ones. Working with this tool is quick, and the advantage of its functions is savings, especially with large volumes of work. To work you need a short piece of metal strip, a bolt and a couple of nuts.
