ABSTRACT:
The present invention relates to clamps which frictionally and releasibly engage two axially aligned pipes to prevent forced separation of the pipes. More specifically, the present invention relates to a sewer line vent clamp assembly having a novel double circumferential ribbing for effectively gripping thin-walled polyvinylchloride (PVC) tubing, and releasibly fixing a thin-walled PVC pipe to a standard, flanged sewer trap. The present invention effectively connects a PVC vent pipe to a sewer trap without piercing or distorting the thin wall of the PVC vent pipe.
