Claims

[Scope of claim for utility model registration] (1) Piping insertion hole 2 is provided through the axis of the bottom wall,
In addition, a retainer member 1 is formed of a bottomed cylindrical body and has a plurality of locking claw walls 3 integrally projecting toward the rear inner side in a tapered slope shape on the circumferential side wall, and a step provided on the inner side of the connecting side end. It consists of a socket member 4 which has a communication hole 5 in its axial center connected to an enlarged diameter part 6 and a hooking groove 7 in its outer peripheral wall, and when connecting a pipe P, the socket member 4 is used to connect the pipe P. The outer annular bulging wall P' with the seal ring 8 attached to the back surface provided on the connecting end side is inserted into the insertion hole 2 of the retainer member 1 near the end thereof, and the outer annular bulging wall P' is expanded in diameter with a step. 6, as the retainer member is attached to the socket member 4, the locking pawl wall 3 is resiliently engaged in the engaging groove 7 on the socket member side in the relative direction. A fitting for connecting small-diameter piping characterized by being configured so as to be fitted. (2) In claim 1, the engaging groove 7 is provided in an annular manner in the circumferential direction of the outer peripheral wall of the socket member 4, or is provided as a stepped portion continuing to a groove formed in the outer peripheral wall in the longitudinal direction of the axis. A joint for connecting small diameter pipes, characterized in that a plurality of are provided at intervals in the circumferential direction. (3) In claim 1, a collar 9 is interposed between the bottom wall of the retainer member 1 and the seal ring 8, or an annular projecting wall 9' protruding from the bottom wall of the retainer member 1 is used as a seal. A joint for connecting small diameter pipes, characterized in that it is configured to abut on a ring 8.
