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.
Raccord de tuyau en plastique (10) comprenant une longueur de tuyau (12) ayant une paroi en plastique (14), un raidisseur de tuyau essentiellement rigide (32) placé à l'intérieur du tuyau et un collier essentiellement rigide (34) placé autour du tuyau à l'extérieur de la paroi du tuyau (14), le collier ayant un retrait (40) à l'intérieur. Le raidisseur (32) et le collier (34) sont placés de façon qu'une partie (50) de la paroi du tuyau soit placée entre le raidisseur (32) et le retrait du collier (40) et qu'une partie (52) du raidisseur soit déviée vers l'extérieur contre la partie (50) de la paroi pour créer l'espace nécessaire à l'insertion cette dernière dans le retrait du collier (40), assurant ainsi une prise solide avec le tuyau, ce qui permet au collier de servir de fixation pour un autre élément comme un joint mécanique (30). On décrit également la méthode de fabrication du raccord (10).
