ABSTRACT:
A fastener for connecting a cover plate to an electrical box housing comprises a prong secured to a base which is attached to the rear face of the cover plate. The fastener comprises a prong having a compressible, radially expanded portion which is received within an aperture formed in the electrical box housing. The expanded portion is resiliently urged toward a radial dimension exceeding the diameter of the aperture so that the prong can be tightly engaged within a bore or behind an aperture in a plate. The fastener can be easily attached to previously known cover plates by glueing, welding, or the like. However, the preferred construction of the fastener comprises a filiform element bent to form a planar base and a prong extending substantially perpendicular to the base, and wherein the base is secured to the rear face of the cover plate.
