ABSTRACT:
A plastic pipe adaptor (10) includes a length of pipe (12) having a plastic pipe wall (14) with a substantially rigid pipe stiffener (32) disposed inside the pipe and a substantially rigid collar (34) disposed about the pipe exteriorly of the pipe wall (14), the collar having a recess (40) therein. The stiffener (32) and collar (34) are positioned such that a portion (50) of the plastic pipe wall is disposed between the stiffener (32) and the collar recess (40) and at least a portion (52) of the pipe stiffener is deflected outwardly against the pipe wall portion (50) by an amount sufficient to wedge the pipe wall portion (50) into engagement with the collar recess (40). The result is a firm grip to the pipe which allows the collar to serve as an attachment to another member such as a mechanical joint (30). A method of making the adaptor (10) is also described.
