<p>A locking member (86) of a locking piece (78) equipped to a locking component (16) moves between a standby position disposed inside a gap (44) provided between a projecting part (40) and a projecting part (42) provided to a connecting part (18) of a locking part (36), and an connected position disposed below the projecting part (42), such that when a pipe (12) is inserted up to a set position the locking component (16) moves to the connected position and is locked by the locking piece (78). Further, when an elastic piece (80) and the locking piece (78) are in contact with a flange (12A) of the pipe (12) they accumulate a biasing force which expands outwards, such that when the lock is released in the standby position of the locking member (86) it returns to its original position following the outer edge of the flange (12A) and releases the biasing force.</p> |
