Claims

[Claims for Utility Model Registration] ■ An inner peripheral surface that contacts the bottom surface of an annular groove 4 formed on the outer periphery of the end of the socket tube 3 between the socket tube 2 and the socket tube 3 inserted therein. a hard retaining ring 5, a backup ring 6 therefor, and an elastic backing 7.
．． 8 is inserted, and the elastic backing 7.8 is pressed against the opposing surfaces of the two tubes 2 and 3 by applying a pressing force in the tube axis direction as a member to seal the socket tube 2. In a pipe joint that is provided with a pressing member 9 that performs A ring member 10 that is in contact with the inner surface 1a of the end portion and is deformed or destroyed when subjected to a set compressive force that is less than the compressive strength of both the pipes 2.3 and the retaining ring 5.
A pipe joint characterized by having: (2) The inner surface 1a of the end of the socket pipe 2 is formed into an outwardly expanding tapered surface, and the outer circumferential surfaces of the retaining ring 5 and the ring member 10 are the same as or approximately the same as the outwardly expanding tapered inner surface 1a. The pipe joint according to claim 0, which is formed on tapered surfaces having the same slope. (2) At least a surface portion of the annular groove 4 corresponding to the pipe axis direction on the inner surface 1a of the end portion of the socket pipe 2 is formed as a surface parallel or almost parallel to the pipe axis. Pipe fittings described in section ■. (2) The pipe joint according to any one of claims 0 to 0, wherein the ring member 10 is made of synthetic resin. (2) The pipe joint according to any one of claims 0 to 0, wherein the ring member 10 is made of hard elastic rubber.
