A connector includes a housing and a release button. The housing defines a recess for receiving a latch member of a receptacle. The release button is operable to cause displacement of the latch member from the recess and has a surface that aligns with a surface portion of the housing when disconnected from the receptacle. The surface of the release button protrudes from the surface portion of the housing when the connector is connected to the receptacle to provide a visual indication that the connector is connected to the receptacle.
