An insulative connector body is accommodated in a conductive shield case. A conductive contact is provided on the connector body. An insulative cover is accommodated in the shield case so as to be slidable between a first position for concealing the contact and a second position for exposing a part of the contact and allowing a mating connector to electrically contact therewith. A conductive shield member is attached onto a front face of the cover which faces the mating connector.
