Abstract
Abstract A one-piece clip is provided which can be quickly and easily secured to the flange of a channel stud and to a conduit box without the aid of fastening means other than that which is an integral part of the clip. The clip is provided with barbs or prongs which engage the web and flange lip of the stud for preventing displacement of the clip relatively to the stud and box. A feature of the invention is the provision of means formed integrally with the clip for the securement to the clip of the ground wire of a three wire system, as well as means in the clip for receiving a screwdriver or the like for the purpose of biasing portions of the clip away from other portions, whereby to facilitate attachment of the clip to the stud and box.
