Claim:
A connector comprising: a housing having a front end that is connectable to a mating housing and a rear end opposite the front end, the housing having at least two terminal fittings, at least one opening in a surface of the housing between the front and rear ends where the terminal fittings are exposed; a lock arm projecting from the surface of the housing and holding the housing in a connected state with the mating housing; at least one connection detecting member mounted into the housing and movable with respect to the housing between a retracted position projecting rearward on the housing and a detection position forward of the retracted position, the connection detecting member being held at the retracted position with a forward movement thereof relative to the housing prevented, and permitted to move forward to the detection position by being released from a movement prevented state relative to the housing as the housing is properly connected to the mating housing; and at least one shorting terminal mounted on the connection detection member and normally held in contact with the respective terminal fittings via the opening to short the terminal fittings and moves forward from the opening to release the shorted state of the terminal fittings as the two housings are connected properly and the connection detecting member reaches the detection position; wherein the connection detecting member is arranged at a height position at least partly overlapping a deformation space for the lock arm between the housing and the lock arm.
