摘要： A pipe-end-connecting joint comprisse a nipple 1 inserted in the pipe end, a holder 2 for tightening the outer circumference of the pipe end, and an elastic packing 3 divided into half parts and attached in the holder 2. The nipple 1 includes a tubular portion 11 provided in one longitudinal end side thereof so as to be inserted in the pipe end, a connection portion 12 provided in the other longitudinal end side thereof so as to be connected to another joint, and a flange portion 13 provided in a longitudinal intermediate portion thereof so as to protrude outward. The holder 2 is divided longitudinally into two split parts 2A and 2B so that each of the two split parts 2A and 2B has an semicircularly formed inner circumferential surface 21, and each of the two split parts 2A and 2B has one longitudinal end side in which one of the half parts of the elastic packing is mounted, and has the other longitudinal end side in which a ring-like groove 23 is formed so as to be fitted to the flange portion 13, and further has a longitudinally intermediate portion between the one and the other longitudinal end sides in which a spiral corrugated portion 22 is formed along the outer circumferential surface of the pipe P, the spiral corrugated portion 22 having a spiral protruding portion 24 an inner diameter of which is smaller than an outer diameter of a trough portion r of the pipe P, the two split parts 2A and 2B having holes for insertion of connection bolts.
