Fastening device

Claim 1

A fastening device adapted for insertion through an aperture in a panel comprising: a deformable loop-like body member adapted for mounting with said support member; said body of a substantially V-shaped configuration defining an opening at the unconnected ends of its legs, said body member having exterior panel receiving grooves adjacent said opening which receive said panel therein when said body member is inserted connected leg end first through said aperture causing the legs of said V-shaped body member to flex inwardly; a plunger member mounted on said body member adapted for insertion into said opening, said plunger member having a portion configured generally complementary to said opening for seating engagement of said plunger member within said body member and carrying cam-like locking means adapted for interlocking in snap-action relation said plunger member with said body member in the installed position of said device, said pLunger member being initially integrally connected to said body member adjacent one end thereof adapted to be sheared therefrom and moved into said body member, said plunger member being partially deformable adjacent the connected end to facilitate insertion of said plunger member into said body member; said plunger member of a generally wedge-shaped configuration, in front elevation, including oppositely disposed side walls inclined toward one another in a direction toward said body member; and said opening being tapered adjacent the unconnected ends of said legs of said body member and conforming to the configuration of said plunger member to effectuate relatively permanent seating engagement of said plunger member within said loop-like body member in the installed position of said device.
