Abstract
A clip-on assembly that can resist detachment of a plastic picket cap member from a plastic picket member when significant pulling force is applied to the cap member. The assembly includes a single clip constructed as a bushing-like member whose side walls are preferably provided with at least one outwardly projecting retention barb adapted for secure embedment into the inner side wall surfaces of a picket member when the assembly is inserted therein. The legs of the cap member upon which the clip is installed are very stiff by virtue of being reinforced by plates that resist deflection of the legs when inserted in the clip. The reinforcement plates are preferably dimensioned to inhibit inward flexure of the side walls of the clip and ensure embedment of the retention barb into the picket member.
