Clamps for corrugated pipes are available in various sizes adapted to different nominal diameters and are equipped with a fir tree fastener intended for quick insertion into a drilled hole. Thanks to the multiple lamellas of the fir tree fastener, these types of clamps can also be mounted in non-through holes. The pipe is locked in the clamp, which ensures secure fixation. The profile of the clamp has an internal flange that prevents the pipe from shifting in the clamp. CTC clamps are used, for example, in the automotive and electrical industries, in the production of harnesses, and wherever corrugated pipes need to be quickly and securely mounted.
