Claims

[Claims for Utility Model Registration] (1) A joint body having a tapered connecting port into which a pipe is inserted and a stepped portion formed at the rear of the connecting port and having a smaller diameter on the rear side. , in a space surrounded by the joint body and the pipe inserted into the joint body from the connection port, an elastic annular seal member and a ring-shaped seal member disposed closer to the connection port end than the seal member and configured to be connected to the pipe. an insert that includes a retaining ring that makes the pipe removable by displacing the retaining ring with respect to the pipe, and has a through hole drilled in the connection opening for inserting a pipe removal tool that displaces the retaining ring with respect to the pipe; In the joint, an annular retainer having an outer diameter equal to the inner diameter of the inner circumferential tapered surface of the connection port at a predetermined position closer to the seal member than the through-hole bored part is interposed between the seal member and the retaining ring. A plug-in joint characterized by: (2) A pipe removal tool comprising an insertion portion for inserting into the through hole of the insertion joint according to claim 1, and the insertion portion is formed in the shape of an eccentric cam in the circumferential direction.
