Claims

[Scope of utility model registration request]

Consists of a male joint and a female joint that are detachable from each other,
When the two are connected, the male joint has a single annular recess formed in the circumferential direction on the outer periphery of both joints, which are located on a plane perpendicular to the axis, and the female joint has a pair of opposing notches. A groove is formed by penetrating near the center in the direction of the inner and outer surfaces of the female joint, and engages the opposite leg pieces of the U-shaped locking tool from the direction of the cutting line of the annular groove of the male joint and the notch groove of the female joint. In the pipe joint having the structure, one leg of the U-shaped locking device is formed long, and a notch is formed at the same position as the lower end of the other leg, and one of the legs is inserted through the notch. A bent piece is formed at the lower end of the leg piece, a substantially isosceles trapezoid-shaped step part with openings on the end faces facing each other is provided in the center part of both leg pieces, and a curved part is provided on the inside. A pipe joint in which the resiliency of the stepped portion applies pressure force between the end of the connected male joint and the sealing member inside the female joint.
