Claims

[Scope of utility model registration request]

A locking ball 6 is provided near the plug insertion opening of the socket 1 so as to be freely protrusive and retractable in a centrifugal direction, and an operating ring 7 that restricts or releases the outward movement of the ball is attached to the outer peripheral surface of the socket by a spring 8.
The socket and the plug are slidably provided by applying force to the circumferential groove 25 provided on the outer circumferential surface of the plug, and the locking ball 6 is engaged with or released from the circumferential groove 25, so that both the socket and the plug can be freely connected to and separated from each other. In the joint, a locking ball bearing ring 10 that is pushed into the plug insertion opening 4 of the socket 1 when the plug is inserted is biased by a spring toward the direction of the plug insertion opening of the socket, and is further provided at the back of the fluid flow path of the socket. A valve body 15 is provided concentrically with the locking ball bearing ring and has a cylindrical front portion 19 that slides within the ring, and is slidable in the axial direction with a spring 20 interposed therebetween. A pipe joint is provided with a communication hole 17 penetrating the inner and outer peripheral surfaces thereof, and a seal ring 12 provided at the front open end of the locking ball support ring 10 to hermetically seal the end face of the insertion plug.
