Claims (1)

[Scope of utility model registration request] One end of the pipe is inserted into the enlarged diameter part of the joint body, a packing is interposed between the inner surface of the enlarged diameter part and the outer surface of the pipe, and the packing is inserted into the joint body through a ring placed on the end side of the packing. A push ring is provided that is pushed into the center and has a tapered inner surface that narrows toward the end, and a pipe removal stopper is installed between the tapered inner surface and the outer surface of the pipe to tighten the push ring toward the joint body. In a pipe joint that tightens a pipe by attaching the pipe, the retainer includes a rake member having an annular blade portion on the inside and a smooth conical surface on the outside, and the rake member is arranged around the outer periphery of the pipe. 1. A pipe joint comprising an elastic ring connected and held in an annular shape, the inner surface of the elastic ring being in contact with the outer periphery of the pipe, and the outer surface of the elastic ring being in contact with the tapered inner surface of the press ring.
