Clamps for corrugated pipe mounting are available in various sizes suitable for different nominal diameters and are equipped with a fir tree fastening designed for quick insertion into a drilled hole. Thanks to the many lamellae of the fir tree fastening, these types of clamps can also be mounted in non-through holes. The pipe is snapped into the clamp, which ensures a secure attachment. 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 the production of harnesses, and wherever corrugated pipes need to be quickly and securely mounted.
