Claims

[Scope of utility model registration request]

Two small-diameter stepped portions 10 are provided on the inner circumferential surface of the connector body 1.
A, a large diameter stepped portion 10B is provided, and the large diameter stepped portion 1 on the opening side
A spring receiver 3 and a stop ring 5 are fitted and fixed in 0B, and a plurality of elastic claws 11 are inserted between the spring receiver 3 and the stop ring 5 to fit into a stopper groove 8 provided on the outer periphery of the inserted pipe 7A. The pipe 7A is inserted into the O-ring chamber 9 formed by the small-diameter stepped portion 10A at the back and the center end surface of the spring receiver 3, with the annular spring 4 provided on the circumference for preventing the pipe from coming off fitted.
Fit the O-ring 2 that gas-seals the tip of the
In the pipe connector, a push fitting 6 for removing a pipe is slidably fitted on the inner circumferential side of the stop ring 5, one end of which is exposed and whose tip presses the elastic claw 11 when pushed in. An annular groove 3' is formed between the side wall surface and the stop ring 5,
The continuous outer peripheral edge 4' of the annular spring 4 for preventing slipping out is fitted into the annular groove 4 so as to be able to shift freely in the axial direction, and is curved together with the elastic claw 11 due to the pressing force applied to the elastic claw 11. A one-touch pipe connector configured to be supported by the spring receiver 3 and the stop ring 5.
