PROBLEM TO BE SOLVED: To surely hold a locked state of a connector housing. SOLUTION: A lock arm is composed of a locking operation member 18 to be locked with a locking projection 6 of a mating-connector housing, and a releasing operation member 17 mounted at the back of the locking operation member 18 for releasing the locking with the locking projection 6. The releasing operation member 17 is advanceably and retractably assembled in the locking operation part, and is advanced when both connector housings 1 and 2 are normally engaged. Whereby the releasing operation member 17 is passed through a supporting part 19 of the locking operation part, which prevents the lock arm 16 from being deflected to be released from the locking with the locking projection 6.
