A coupling for connecting one or more pipes or conduits (12). The coupling (10) includes at least one wedge-shaped gasket (22) extending around the coupling. The wedge-shaped gasket (22) includes an outer sloped or inclined surface (24), an inner surface (26), and a pair of opposed ends (28, 30) where one end is higher than the other. In use, a pipe, duct (12) or conduit is inserted over one end portion of the coupling (10) such that as the pipe or conduit is moved or slipped over the wedge-shaped gasket (22), the gasket compresses and forms a seal between the coupling and a portion of the inner surface of the pipe or conduit.

L'invention concerne un raccord servant à connecter un ou plusieurs tuyaux ou conduits (12). Le raccord (10) comprend au moins un joint statique cunéiforme (22) entourant le raccord. Le joint statique cunéiforme (22) comprend une surface extérieure inclinée (24), une surface intérieure (26), et deux extrémités opposées (28, 30) dont l'une est plus haute que l'autre. Pendant l'utilisation, un tuyau, une canalisation (12) ou un conduit est inséré sur une partie d'extrémité du raccord (10) de sorte que, lorsque le tuyau ou conduit est déplacé ou glissé sur le joint statique cunéiforme (22), ce dernier se comprime et forme un joint d'étanchéité entre le raccord et une partie de la surface intérieure du tuyau ou conduit.
