<p>An object of the present invention is to enable a judgment to be more securely made as to whether or not locking has been properly effected. A female housing 30 is provided with an assisting resilient piece 50 in addition to a lock arm 40, and the assisting resilient piece 50 is resiliently deformed by pressing portions 46 pressing the bottoms of pressable grooves 54 as the lock arm 40 is resiliently deformed. The assisting resilient piece 50 is also resiliently restored as the lock arm 40 is resiliently restored, whereby a second hitting portion 52 at the leading end thereof hits a second hittable portion 27 that is the inner surface of the back side of an upper wall 19 of a mating male housing 10. This hitting is set to occur simultaneously with the hitting of a first hitting portion 45 of the lock arm 40 against a first hittable portion 25 that is the lower surface of a front portion 23 of a lock groove 20. Since the lock arm 40 is resiliently restored by a large resilient restoring force with the addition of a resilient restoring force of the assisting resilient piece 50, a large hitting sound is given out. Further, a hitting sound of the assisting resilient piece 50 itself is also added, whereby quite a large hitting sound can be obtained.</p> |
