Lock detecting connector
 A contact face 16 of a rib 15 is arranged to be inclined downwards with respect to the fitting direction of connector housings 10,20. Detecting terminal fittings 14 make contact with the contact face 16 and are resiliently bent in a predetermined manner. If the rib 15 should be bent away from the detecting terminal fittings 14, the detecting terminal fittings 14 follow due to their inherent resilience and thereby maintain contact with the contact face 16.
