Claims

[Scope of utility model registration request]

It is arranged between a pipe and a cylindrical joint body into which it is inserted or a push ring that is screwed onto the joint body, and moves with the pipe as the pipe moves in the drawing direction, and moves inside the joint body or push ring. A retaining member that is pressed by a tapered surface formed on the circumferential surface and bites into the pipe, and the retaining member is formed in an annular shape with a notched portion that allows diameter expansion and contraction, and has an inner diameter. The periphery has a plurality of bite teeth that bite into the outer surface of the tube in the axial direction, and the tube insertion side end is formed into an inverted surface that goes around to the opposite end of the tube, and also comes into contact with the tapered surface. A member for preventing a pipe from coming off from a joint body, characterized in that a contacting portion thereof is formed into a curved shape.
