管継手。[Claim for Utility Model Registration] Consisting of a socket and a plug, the socket has an operating sleeve on its outer circumferential surface that is biased in the axial direction by a compression spring, and is locked at the inner circumferential surface of the sleeve when connected to the plug. In a pipe joint, the plug has a pressing surface that presses the lock in the centripetal direction, and the plug has an inverted trapezoidal circumferential groove that engages the lock when connected to the socket. The circumferential surface is formed into an inclined surface to press the lock in the centripetal direction in cooperation with the axial compression spring that biases the sleeve, and also seals the outer circumferential surface of the plug with a seal ring for sealing the end surface of the plug. The seal ring for end sealing is made of a cold-resistant material, and the seal ring for sealing the end face has a U-shaped cross section, and is fitted into the fluid passage with the opening of the groove oriented in the centripetal direction to seal the outer periphery. 1. A low-temperature directing joint characterized in that the seal ring has a U-shaped cross section and is fitted into a fluid passage with the opening of the groove oriented in the axial direction of the fluid passage.
