Claim:
A connector connectable to a socket element supporting a pair of fitting elements, comprising: a plug element which supports a pair of fitted elements to be electrically connected to the pair of fitting elements, and is inserted into the socket element and engages with the socket element; a short-circuiting element which includes a short-circuiting piece for electrically short-circuiting the pair of fitting elements, and is attached to the socket element; and a latching element which is latched on the plug element at a first latching position and a second latching position, wherein the latching element is movable between the first latching position and the second latching position, and in a state where the plug element is inserted into the socket element, when the latching element is at the second latching position, the short-circuiting piece moves to the non-short-circuit position, either the latching element or the short-circuiting element has a latch portion formed in a projecting manner, and the other of these has a latch receiving portion formed so as to engage with the latch portion, and in the state where the plug element is inserted into the socket element, when the latching element is at the second latching position, the latch portion and the latch receiving portion engage with each other.
