A keyway opening is defined by the body and the clip comprises a transverse portion and a pair of legs extending outwardly from the transverse portion with contact elements defined by each of the legs extending inwardly toward the keyway opening and with openings defined by the body communicating with said keyway opening for receiving the contact elements. A contact band is carried by the key-like device whereby insertion of the key-like device into the keyway opening brings the contact band into electrical contact with at least one of the contact elements.
