Fastening device

The innovation relates to a fastening device Tooth lock for anchoring <ohl strips, cable clamps len and the like. More on a slip-on part, which through

Welding or the like. Is attached to / on a carrier.

Fastening devices are known, but the T.

se tooth lock to unite two-part related objects such as pipe clamps and the like. wherein the lower part and the upper part have ratchet teeth which cooperate conformally when the upper part is slipped onto the lower part. This type of attachment has two parts

items that belong together and do not need to be changed.

Transferring objects is the task of the present innovation. An object formed in one piece is for example

wise a cable clamp, hollow molding, decorative molding that through a special holding part is anchored to the wall of a vehicle body.

According to the innovation, this object is achieved by a push-on part which is arranged on a carrier and has at least one 45

This ring groove engages with the 55 when plugged together

Lock both objects back together as wide as possible by the displacement of the bolt is. This creates an additional radial clamping force on the locking of both objects. 35
