A retaining mechanism, within a lamp socket, includes a single wire spring element mounted external to the lamp socket and protrudes into the lamp socket opening so as to provide insertion interference to ramped projections extending from either end of a lamp wedge base element and frictional retention against the ramped projections when the wedge base element is fully inserted.

A lamp socket for mating with and retaining a generally rectangular cross-sectional base of an incandescent lamp, wherein the lamp base has filament wire leads separately positioned and exposed on its outer side surfaces and ramped retaining projections on its end surfaces, comprising: a unitary molded body defining a socket cavity and having a generally rectangular opening for slideably accepting the base of said incandescent lamp into said socket cavity; a plurality of electrical terminals within said body for compressibly contacting said exposed filament wire leads of said lamp against said base when mated in said socket; means protruding into said socket cavity so as to contact and compress against the upper portion of said ramped retaining projections of said base for removably holding said base tightly within said socket; said holding means is a single piece of spring wire supported on said body and preloaded with sufficient bias to provide a relatively high level of resistance to the removal of said lamp base from said socket; and said generally rectangular opening of said socket cavity contains slots at the ends of its rectangular opening which are respectively configured to accept a ramped retaining projection extending from said lamp base and said spring wire extends transverse to both slots to interfere with the insertion of said lamp base by providing a relatively low level of frictional resistance by contacting and moving outward with respect to said ramped retaining projections during said insertion and retracting inward to capture and hold said ramped retaining projections when said lamp base is fully mated in said socket.
