<p>A pipe coupling includes a cylindrical coupling body (1) made of resin, an O-ring (3) provided between an inner surface (1B) of the coupling body and an outer surface of a pipe end (7) inserted into the coupling body, and a pipe supporting means (4,5,6) between the coupling body and the pipe end (7) for supporting and retaining the O-ring (3) and the pipe end (7) in the coupling body. Plural through-windows (1a) are formed through the outer cylindrical wall of the coupling body (1) at a predetermined distance from an opening end portion (1 D). An elastic retention member (2) passes through the through-windows (1a) and through outer grooves (5c,6c) in the pipe supporting means (4,5,6). The pipe supporting means (4,5,6) is made of reinforced resin. At least one inner annular groove (5h,6h) is formed at an inner surface of the pipe supporting means (4,5,6) for engaging with an annular outer projecting portion (7a) formed at the outer surface of the pipe end (7).</p> |
