Claim 1

A spring clip adapted to be applied to a workpiece having an aperture therethrough comprising a head portion having means thereon for overlying the workpiece and means thereon for threadedly engaging a screw turned into said head portion, and an integral shank portion insertable through the aperture in the workpiece, said shank portion including a pair of opposed, axially extending, generally parallel legs bent downwardly from opposed outboard marginal edges of said head portion, each of said legs having material removed therefrom to provide openings therein, said openings being defined by longitudinal and transverse internal marginal edges of said legs, and a pair of opposed retainer lugs joined to said legs proximate their ends remote from said head portion, said lugs flaring outwardly from said legs generally back toward the plane of said head portion and being disposed opposite said openings in said legs and within imaginary planar extensions of said internal marginal edges of said legs, each of said lugs terminating in a free edge spaced from the plane of said head portion, said free edges being disposed at a relatively steep acute angle to the plane of said head portion, said lugs have external surfaces which are transversely arced and tapered longitudinally from said free edges toward the planes of said legs Whereby said lugs present substantially smooth workpiece engageable surfaces facilitating passage of said shank portion through a workpiece aperture, said lugs per se being resiliently compressible toward each other to permit passage of the shank into a workpiece aperture and being resiliently expansible away from each other upon passage through the workpiece aperture to urge said free edges into aggressive engagement with the workpiece.
