A connector module for use with a shielded housing uses a lever-actuated wedge member to lift a flexible locking tab of the shielded housing over a locking pin of the connector module. The wedge member has a pointed end that faces the locking pin so that the wedge member can be slid between the connector module and the shielded housing flexible tab that engages the locking pin. The wedge member is moved by way of a lever within the connector module and which pivots about a fulcrum in the connector module. Moving the lever one direction moves the wedge member in an opposite direction.
