Claims

[Claims for Utility Model Registration] (1) A cylindrical female member and a male member are removably inserted and connected, a ring cap is attached to the outer periphery of the connection side of the female member, and the male member side of the ring cap is attached to the outer periphery of the connection side of the female member. In a pipe joint in which an elongated portion is formed, a cottle ring is disposed inside the elongated portion, and the female and male members are connected via this cottle ring, the proximal end side of the ring cap is formed on the outer periphery of the female member. A fitting part for a joint separation jig is formed on the outer periphery of the male member between the end of the extension part of the ring cap and the proximal end of the male member. The male member is removably fitted to the stepped side of the male member, and the male member side end of the cottering ring is formed with a tapered surface whose diameter expands outward to match the tip of the separation jig. A pipe joint characterized by: (2) A joint separation jig which is attached to the attachment portion of the male member according to claim 1 and separates the joined female and male members, which is formed into a cylindrical shape in the attached state, and whose inner diameter is equal to that of the male member. The outer diameter is slightly larger than the outer diameter of the mounting part, and the outer diameter is slightly larger than the outer diameter of the stepped part formed on the outer periphery of the male member. A joint separating jig, which has a tapered surface that matches the tapered surface of the ring and can be inserted into the lower surface of the stub ring, and is divided into a plurality of pieces in the direction of the center line or formed integrally.
