Claims (1)

[Claims for Utility Model Registration] The socket pipe A is interposed between a socket pipe A or a push ring C connected to the socket pipe A and a connecting pipe B inserted into the socket pipe A. When a pulling force is applied to the connecting pipe B, the connecting pipe B comes into contact with the socket pipe A or the push ring C and is prevented from moving in the pulling direction with respect to the socket pipe A or the push ring C, and the connecting pipe B
A C-shaped retaining body 2 is provided which is pressed against the outer circumferential surface of the connecting pipe B, and when the retaining body 2 is pressed against the outer circumferential surface of the connecting pipe B,
The plurality of protrusions 3 that bite into the outer circumferential surface of the connecting tube B and prevent the connecting tube B from moving in the drawing direction are arranged in the circumferential direction or in the helical direction around the tube axis. It is a connecting pipe removal stopper formed at intervals in the helical direction and the tube axis direction, and the protrusion 3 has the same protrusion height over the entire length or almost the entire length in the circumferential direction or the helical direction. A stopper for connecting pipes formed in The connecting pipe retainer according to claim 1, wherein the retainer body 2 and the protrusion 3 are integrally manufactured by sand casting.
