PROBLEM TO BE SOLVED: To facilitate assembly while simplifying pipe connecting work and to firmly maintain pipe connection. SOLUTION: In this joint, a tapered face 6 contracted in diameter toward an opening 2 is formed at the inner peripheral part of each half part of a cylindrical body 1 to joint pipes A, B, and a diameter-contractible elastic wedge ring 7 is disposed at the large inner diameter part of the tapered face 6. In order to push out the wedge ring 7 along the tapered face 6 to contract the diameter when the pipes A, B are about to slip off, a rubber ring 10 capable of coming in close contact with the pipes A, B is provided adjacently to the wedge ring 7 being engagedly held to a sliding ring smoothly slidable along the inner periphery of the cylindrical body 1. When the wedge ring 7 is put in the diameter contracted state, the wedge ring 7 bites into the outer peripheral surfaces of the pipes A, B to impede the slip-off of the pipes A, B.
