Abstract

L'invention concerne un accessoire de canalisation se présentant sous la forme d'une pièce en forme de T (34), pourvu de trois manchons (36.1, 36.2, 36.3) constituant des raccords. Chaque manchon comprend un filetage interne (16.1, 16.2, 16.3), et des conicités (20.1, 20.2, 20.3). Des écrous (24.1, 24.2, 24.3) présentant un filetage externe (28.1, 28.2, 28.3), des bouts mâles (30.1, 30.2, 30.3) et des conicités (32.1, 32.2, 32.3) sont vissés dans les manchons. Les conicités (20.1, 20.2, 20.3) contraignent les extrémités libres des bouts mâles (30.1, 30.2, 30.3) vers l'avant de manière que ceux-ci mordent dans les extrémités des tuyaux (P1, P2, P3). Dans un autre mode de réalisation, les conicités présentent différentes inclinaisons les unes par rapport aux autres. Et encore dans un autre mode de réalisation, chaque conicité présente plusieurs inclinaisons.
