Abstract: An electrical wiring box for mounting an electrical device therein by means of push inserted screws is provided. The box is defined in part by a pair of parallel spaced sidewalls and a pair of parallel spaced end walls. A mounting bracket is formed on each end wall for the snap mounting of a resilient screw receiving spring clip. Each spring clip is formed of a strip of resilient metal bent to define a base portion, upwardly disposed side portions and inwardly disposed top portions, such that the ends of the strip are positioned adjacent one another. The ends of the top portions are bent downwardly and inwardly of the clip to define a spring receiving space therebetween. The base portion has a spring receiving opening defined by a pair of downwardly bent tabs which is aligned with the space defined by the ends of the strip. In operation the spring clips are snapped into engagement with the respective brackets and the electrical device positioned within the wiring box for mounting.
