ABSTRACT:
The fastener comprises a head and a snap-engagement foot comprising a rigid core and curved flexible wings. Each wing has a convex surface bordered by said core, by a longitudinal edge surface and by a transverse edge surface. Each transverse edge surface has, viewed by an observer viewing said convex surface, a V-shape of which the point, which is directed outwardly, is located at said inflection plane. The core is a hub about which at least three said wings are regularly spaced. Each wing comprises a corner delimited by said longitudinal edge surface and by a shoulder and a web less thick than the corner, disposed between the hub and the shoulder. Each wing is adapted to flex by elastic deformation towards the convex surface of the neighboring wing.
