A spring clip for securing a terminal connector to an apertured workpiece includes a shank portion having a pair of opposed legs carrying snap lugs disposed opposite internal openings in the legs. The lugs are compressible into the openings in the legs and toward each other during insertion of the shank portion in a workpiece aperture. Each of the lugs is formed as a U-shaped bight having a longitudinally tapered and transversely arced external surface which facilitates inward, camming compression of the lugs during shank insertion. While the lugs are resilient in the sense that they are compressible as aforesaid and will snap apart to engage the workpiece subsequent to full insertion, the U-shaped bight form provides for substantial rigidity in each lug per se which in turn provides for aggressive snap engagement of the workpiece. The workpiece engaging edges of each of the lugs are disposed at a relatively steep acute angle to the head of the clip to thereby render a given size clip effective for use over a relatively wide range of workpiece thicknesses and aperture widths and to automatically compensate for thickness variations adjacent the aperture of an individual workpiece.
