PROBLEM TO BE SOLVED: To provide a joint capable of ensuring a sealing condition securely even if length in the direction of axial line of a joint body is made comparatively short. SOLUTION: This joint is provided with the joint body 2 having a seal storage part, a pressing ring 4 mounted on the joint body 2, and a locking seal body 20 stored in the seal storage part of the joint body 2 and a fireproof packing body 22. The locking seal body 20 has an annular seal part 24 and a locking ball 26 arranged in the annular seal part 24, and the locking ball 26 is locked in a trough part 32 of a corrugate pipe 30. Inclined faces 34, 40 are provided on an end face in which the locking seal body 20 and the fireproof packing body 22 oppose mutually. When one crest at a tip of the corrugate pipe 30 protrudes by crossing the locking ball 26, the locking ball 26 locks the trough part 32 of the corrugate pipe, and a crest part 54 on a tip side of the corrugate pipe 30 is sealed on an inner peripheral face of the annular seal part 24.
