The invention relates to a pipe clamp for attaching a duct to a base surface. The pipe clamp comprises 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, for engaging on the tightening element. The spring nut is designed such that the tightening element 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 with a through-opening for the shank, as well as a set of resilient hinge parts and a set of connecting arms. 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.
Pipe clamp for attaching a pipe to a wall, ceiling or another base, comprising:
Pipe clamp according to one of the preceding claims, in which the free end of the resilient lip comprises an edge which engages on the shank.
Pipe clamp according to one of the preceding claims, in which the connecting arms extend substantially parallel to the baseplate.
Pipe clamp according to one of the preceding claims, in which the resilient lips of the first set extend substantially parallel to the baseplate.
Pipe clamp according to one of the preceding claims, in which the resilient hinge parts associated with a set of lips are situated on the same side of the baseplate.
Pipe clamp according to one of the preceding claims, in which the spring nut comprises stop members which are arranged on the baseplate on the side facing the resilient lips at the location of a connecting arm and which detain the connecting arms or resilient lips when the tightening element is retracted.
Pipe clamp according to one of the preceding claims, in which at least one stop member is arranged on the baseplate on the side facing the resilient lips, which detains the relevant resilient lip when the tightening element is retracted.
Pipe clamp according to one of the preceding claims, in which a second set of resilient lips with free ends facing one another is integrally formed on the baseplate.
Pipe clamp according to one of the preceding claims, in which an integral securing element is provided on the baseplate which connects the spring nut to the clamp body.
Pipe clamp according to one of the preceding claims, in which a flange is provided at the second end of the clamp body.
Pipe clamp according to one of the preceding claims, in which the shank of the tightening element is provided with external screw thread or the like.
Spring nut for a pipe clamp, which spring nut is shaped as described in one of the preceding claims.
