A female connector (F) has a housing (10) with a front end and cavities (11) extend to the front end. Terminal fittings (40) are mounted in the cavities (11). A front wall (50) is mounted on the front end of the housing (10) and is formed with tab insertion holes (51) that can communicate with cavities (11). An operable surface (59A) is exposed at an end surface of the front wall (50). The front wall (50) can be moved from a full locking position to a partial locking position along the front end of the housing (10) by pushing this operable surface (59A). Portions of the end surface of the front wall (50) other than the operable surface (59A) are covered at least partly by an wall (26) of the housing (10) to limit movement of the front wall (50).
