I have never been one for spending money i dont need to (yes i did need those seat belt bold covers!!) i set about making my own.
So what i used was 2 6" nails and 2 good cable ties (dont use rubbish ones as you really dont want them to fail) per pipe, i needed to clamp two pipes
so what you need to do is lay two nails head to toe and just cable tie one end.
So take the clamp and place the hose between the two nails and close the other end of the nails to clamp the pipe. Use a pair of grips etc to close the nails tight enough to trap the pipe.
Place a cable tie on the other end and tighten it up as tighten as mush as you can, remove the plier and there you have a clamped pipe




Hope this is of use to some one
