Upon fitting a female housing ( 10 ) into a receptacle ( 44 ) of a male housing ( 40 ), metallic lock portions ( 42 ) are hidden behind receiving portions ( 12 ) when viewed from the front side of the receptacle ( 44 ) at an initial stage. When the lock portions ( 42 ) move over the receiving portions ( 12 ) while being resiliently deformed as this fitting operation progresses, the lock portions ( 42 ) are engaged with the receiving portions ( 12 ) and can be visually confirmed from the front side of the receptacle ( 44 ). Thus, the properly connected state of the two housings ( 10, 40 ) can be detected by visually confirming the lock portions ( 42 ) from the front side of the receptacle ( 44 ).
