A cable interface (10) operable to interface a cable trunk line with an electronic equipment enclosure (12) via a pendant cable (14), thereby providing for quick and convenient connection and disconnection, when desired, of the equipment enclosure (12) from the pendant cable (14). The equipment enclosure (12) may house a variety of electronic equipment, such as, for example, telecommunications, signaling, and similar electronic equipment, including, for example, repeater and doubler cards. The preferred cable interface (10) broadly comprises a first connector half (16); a mounting plate (18); a second connector half (20); a free-spinning nut (22); a security cover (24); and a flexible cable extension (26). The security cover (24) cooperates with the second connector half (20) to restrict unauthorized access to the connection.
