摘要

A pipe joint for joining two pipes (10,11) end to end comprises a hollow cylindrical spigot portion (2) having an annular projection (1) on the outer periphery of a base end thereof, a hollow cylindrical socket portion (4) having an inside diameter approximately equal to the outside diameter of the spigot portion (2) and formed with two opposed apertures (3) in its peripheral wall close to a forward end thereof and with a stepped part (4b) on the inner surface of the peripheral wall for the projection (1) to come into contact with, the stepped part (4b) being closer to a base end of the socket portion (4) than the apertures (3), and a stopper (6) having a pair of circular-arc resilient legs (5) fittable into the respective apertures (3) from outside to project inward and each having a slanting inner surface (5a), the legs (5) being opposed to each other for the inwardly curved surfaces thereof to face each other. The projection (1) is fixedly held between the stepped part (4b) and the legs (5) by inserting the stopper (6) into the apertures (3) with the slanting surfaces (5a) facing toward the insertion side of the spigot portion (2) and inserting the spigot portion (2) into the socket portion (4) until the projection (1) moves past the legs (5). The spigot (2) and socket portions (4) are provided at the joint ends of the two respective pipes (10,11) to be joined.
