Pipe clamp with spring nut

摘要

The invention relates to a pipe clamp (1) for attaching a duct (50) to a base surface. The pipe clamp comprises a clamp body (2) with an aperture (6) for arranging the pipe clamp around the duct, a tightening element (18) for keeping the ends (11,12) of the clamp together, and a spring nut (30) arranged on the second end of the clamp body and provided with a set of resilient lips (33a,33b) with free ends facing one another, for engaging on the tightening element (18). The spring nut (30) is designed such that the tightening element (18) can be pushed relatively far into the spring nut during closure of the pipe clamp and that pulling the tightening element out of the spring nut is prevented. The spring nut comprises a baseplate (31) with a through-opening (32) for the shank (20), as well as a set of resilient hinge parts (36a,36b) and a set of connecting arms (35a,35b). The resilient lips are situated at a distance from the baseplate and, on the end situated opposite the free end, each is connected to an associated connecting arm which extends substantially transversely to the resilient lip. The connecting arm is in turn connected to the baseplate by means of an associated hinge part.
