れていることを特徴とする管継手。[Scope of Claim for Utility Model Registration] A joint that has a screw for screwing into pneumatic equipment, etc., has a locking claw that sinks into the outer periphery of a tube to be inserted into the joint body, and has a locking claw that penetrates the outer periphery of the tube. In a pipe joint that has a release ring that releases the biting and allows the tube to be pulled out, the joint body has a straight-shaped inner part that has at least two stages, a small diameter part and a large diameter part that is larger than the small diameter part. The screw is formed into a cylindrical body, and the screw is made of a metal having a required strength such as stainless steel, and has a flange portion at the base, a male thread portion at the tip, and a diameter between the flange portion and the male thread portion at the middle portion of the joint body. The fitting cylinder is inserted into the joint body from the large diameter side, the male thread protrudes from the small diameter part, and the fitting cylinder fits into the small diameter part. 1. A pipe joint characterized in that the end faces of the flange portions are fixed to the joint body by appropriate fixing means such that the end faces of the flange portions come into contact with the stepped walls of the small diameter portion and the large diameter portion.
