Fastener for truck bed liner

A fastener for insertion through an opening in a first member and providing for thermal expansion and contraction thereof by allowing relative movement between said first member and a rigid support member, a portion of such first member overlying a terminal edge portion of such a rigid support member with said opening being located closely adjacent such terminal edge portion, said fastener comprising:

• a base plate section have a generally planar surface extending along one portion thereof,
• an elongated section having one end portion joined to said base plate section, said elongated section extending outwardly from said planar surface, said elongated section having a free end facing a plane containing said planar surface,
• said elongated section forming a recess adjacent said planar surface which recess extends inwardly of said elongated section and thence towards said free end and forming a pivot at the junction of said recess and said planar surface for pivoting said base plate section to deflect said elongated section, said elongated section always passing around such terminal edge portion of such rigid support member,
• said elongated section having an outer surface configuration adapted to guide a portion of such a first member into a notch projecting inwardly towards the center of said elongated section for forming a wedging surface, said wedging surface and the free end of said elongated section cooperating to clamp the clip for preventing movement thereof, and
• said elongated section including the entire free end thereof being deflected by an elastic stress relative to said base to hold such overlying portions therebetween when such overlying portions are received between said free end and such plane containing said planar surface.
