<p>An object of the present invention is to detect a connected state from the front side of a receptacle.</p><p>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.
