Claims

[Scope of utility model registration request]

A pipe joint that has a seal portion and a lock portion between a socket and an insertion port, and a gasket is positioned in a groove formed on the inner peripheral surface of the socket, and the gasket connects the socket and the insertion port. At the same time, a groove is provided on the outer circumferential surface of the socket for inserting a lock ring with a predetermined length that takes into account the necessary allowance for pulling out the joint, and screws are installed on the end surface of the socket at appropriate intervals in the circumferential direction. An annular stopper member is attached to the socket end face with one end face in contact with the socket end face by a bolt that is screwed into the screw hole, and one end face of the inner peripheral surface of the stopper member is provided. A side corner portion is notched along the entire length in the circumferential direction to form a notched stepped surface facing the end face of the socket, and the lock ring in the lock ring insertion groove is inserted between the end face of the socket and the notch of the stopper member. 1. A pipe joint characterized in that a lock portion is formed by positioning the lock portion between the pipe joint and the stepped surface.
