Claims

[Scope of utility model registration request]

In a pipe joint in which the socket of one pipe is inserted into the socket of the other pipe to join both pipes, an annular ring is formed between the inner circumferential surface on the rear end side of the socket and the outer circumferential surface on the distal side of the socket. A sealing member is interposed, and an annular socket groove is provided on the inner circumferential surface of the socket on the distal side of the sealing member, and an annular socket groove is provided on the outer peripheral surface of the socket facing the socket groove. , inserting a press ring collar whose diameter can be expanded and contracted into pieces in the circumferential direction onto the outer periphery of the socket having the socket groove, with one end surface of the collar in contact with the sealing member;
A locking protrusion that fits into the insertion slot and locks the inner circumferential surface of the collar, and an annular stepped portion on the outer circumferential surface,
A lock ring is fitted between the annular step portion and the socket groove, the diameter of which can be expanded and contracted in one piece in the circumferential direction, and which prevents the collar from moving to the opposite side of the sealing member. A detachment prevention pipe joint characterized in that the collar is pressed and fixed to a sealing member side by a fastening member via a press ring that is disposed at a position facing a socket end and engaged with the other end surface of the collar.
