A locking assembly used for securing an abutment member to a support member includes a locking stud having a post connected to and disposed outwardly from the abutment member. The post has a longitudinal locking blade connected to and disposed outwardly from the abutment member. The locking blade includes an outwardly disposed inclined surface terminating in a crest edge which comprises a wedge lock for being disposed against an edge of the hole in the support member. An inwardly disposed surface extends from the crest edge. The blade is deflectable at the inwardly disposed inclined surface so that the inwardly disposed inclined surface acts as a cam whereby insertion of the blade into the hole causes an edge of the hole to press against the cam and deflect the blade until the crest edge has passed beyond the hole with the wedge lock preventing removal of the stud from the hole. The post also includes a longitudinally outwardly extending base portion transversely opposite the locking blade. The base portion terminates in an outer edge which is spaced closer to the abutment member than the crest edge. An inwardly sloping surface extends outwardly from the outer edge toward the locking blade. The stud is open in the space opposite the locking blade and outwardly of the inwardly sloping surface. An indexing member secured to the abutment member secures the abutment member to the support surface at a location remote from the locking stud.
