Clamps for corrugated pipe mounting are available in various sizes adapted to different nominal diameters and are equipped with a fir tree clip for quick insertion into a drilled hole. Thanks to the many lamellae of the fir tree clip, such clamps can also be mounted in non-through holes. The pipe is snapped into the clamp, which provides secure mounting. The profile of the clamp has an internal collar that prevents the pipe from sliding in the clamp. CTC clamps are used, for example, in the automotive and electrical industries, in harness production, and wherever corrugated pipes need to be quickly and securely mounted.
