Claims

[Scope of utility model registration request]

A pair of joint pipes are connected to each other to form a pipe joint that connects and holds both joint pipes with a retaining ring, and the connecting end surface of one joint pipe is stepped to form a small diameter pipe portion at its tip. is inserted into the through hole of the other joint pipe from the connecting end side, and a tenth ring is provided between the outer peripheral surface of the pipe part of one joint pipe and the inner peripheral surface of the through hole of the other joint pipe, and A lead ring is provided between the joint pipe and the stepped surface and the connecting end face of the other joint pipe, while a plurality of protrusions are provided protruding from the outer periphery of the connecting end of either one joint pipe or the other joint pipe. , a retaining ring that cannot be removed outwardly from the end is fixed or rotatably provided on the outer periphery of the other connecting end, and the retaining ring has a notch in the inner peripheral surface of the connecting end through which each of the projections is inserted. A pipe joint characterized in that a flange is formed to engage with the projection, so that the projection comes into pressure contact with the inner surface of the flange by the elastic force of the ninth ring when both joint pipes are connected.
