Claims

[Claims for Utility Model Registration] (1) A pipe joint in which one end of the main body is inserted into an attached device and a pipe is detachably connected to the other end, the insertion end of the main body into the attached device a lock ring that is attached to a recess formed in the circumferential direction of the body, and a part of the inner circumference is exposed inside the main body;
An outer periphery provided inside the main body and tapered in the axial direction is brought into sliding contact with the inner periphery of the lock ring, and is displaced in the axial direction by a predetermined jig inserted from the connection side of the pipe. The lock cap has a lock cap that expands and contracts the lock ring in the radial direction, and a lock spring that maintains the expanded state of the lock ring by biasing the lock cap in the axial direction. A pipe joint characterized in that the main body is attached to and detached from the attached device by locking or detaching the lock ring, which is expanded and contracted by the lock cap, in a groove provided therein. (2) Utility model registration claim 1, characterized in that the groove provided on the side of the attached device is a groove carved on the inner periphery of a sleeve that is press-fitted into the attached device. Pipe fittings listed. (3) The pipe joint according to claim 1, wherein planar cutouts are formed at a plurality of locations on the outer periphery of the lock ring. (4) The pipe joint according to claim 1, wherein a plurality of protrusions are formed on the outer periphery of the lock cap, and some of the protrusions are tapered.
