A self-locking cable clamp arrangement includes a bracket and a flexible tab disposed on the bracket. The bracket has a cable mounting region, a first engagement region, and a support region disposed therebetween. A cable can be clamped to the cable mounting region. The support region defining two members spaced apart sufficient to enable an edge of the panel to extend partially therebetween. The flexible tab can be selectively coupled to the cable mounting region and to the first engagement region. The clamp arrangement mounts to the panel by sliding the bracket downwardly through an open-ended slot defined in the panel until the tab is received within a cutout portion of the panel to secure the bracket to the panel.
