The nipple 1 includes a tubular portion 11 to be inserted in the pipe end, a connection portion 12 to be connected to another joint, and a flange portion 13. The holder 2 is divided longitudinally into two split parts 2A and 2B each having a semicircularly formed inner circumferential surface 21, a ring-like groove 23 to be fitted to the flange portion 13, and a 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.
