Abstract
A blind spring clip fastener for insertion in a round hole in a work piece has a head portion and a shank portion extending perpendicular to the head portion. The shank portion comprises a pair of spaced-apart mirror image sections extending from opposite side edges of the head portion, each section including a resilient leg and a pair of wings integral with the free ends of the leg and extending toward the head portion at opposite side edges of the leg. Each wing is shaped so that it has a side edge extending upwardly-outwardly beyond the plane of its leg and a free end extending from a point beyond the plane of the associated leg relatively steeply upwardly-inwardly toward the head portion.
