ABSTRACT:
A pipe clamp for attaching a duct to a base surface. The pipe clamp has a clamp body with an aperture for arranging the pipe clamp around the duct, a tightening element for keeping the ends of the clamp together, and a spring nut arranged on the second end of the clamp body and provided with a set of resilient lips with free ends facing one another, engaging the tightening element. The spring nut has a baseplate with a through-opening for the shank, and a set of connecting arms. The resilient lips are situated at a distance from the baseplate and are respectively connected to an associated connecting arm which extends substantially transversely to the resilient lip.
