Claims (1)

[Claims for Utility Model Registration] An inner circumferential tapered surface that gradually increases in diameter toward the back of the socket on the inner surface of the socket in a pipe joint in which an annular sealing material can be compressed between the inner surface of the socket and the outer surface of the socket. and a rear end surface in the tube radial direction following this inner circumferential tapered surface, and an outer circumferential tapered surface that abuts the inner circumferential tapered surface and an insertion port between the inner circumferential tapered surface and the outer surface of the insertion port. A detachment prevention ring having an inner circumferential latching blade that abuts the outer surface is provided, and the detachment prevention ring has elasticity that abuts the inner end surface and urges the detachment prevention ring toward the opening end of the socket. A separation-preventing pipe fitting characterized by a tongue piece attached.
