継手。 A protrusion is formed on the outer periphery of the tip of a pair of pipes to be connected, and a coupling ring is placed between the ends of the two pipes, and the inner circumferential surface of the coupling ring is connected to the pipe inside the coupling ring. A circumferential groove is formed near both ends of the inner circumferential surface of the coupling ring, and the coupling ring is in sliding contact with the outer circumferential surface of the tube. A locking ring that can be displaced in the pipe radial direction in the circumferential groove following the bending of the pipe is fitted, and a sealing material that is expandable and contractible following the bending of the pipe is fitted between both ends of the coupling ring and the pipe. What is claimed is: 1. A flexible pipe joint, characterized in that a push ring for compressing the sealing material is attached to both ends of the joint ring.
