Abstract
Heat treated spring steel, electroplated with zinc, is formed into clips having a base portion that passes under the base of a railway rail and upstanding end sections that respectively engage and forcefully snap over the opposite lateral edges of the rail base flange. One clip has confronting semi-cylindrical extensions for overlying a section of bond wire to secure the latter in a bight configuration wrapped over the edge of the rail flange. Another clip has a semi-cylindrical extension for securing a section of bond wire to the base flange at the junction with the web of the rail. Angled notches in the edges of the clips provide small barbs that are bent out of the plane of the clip body to bite into the rail when assembled thereto for avoiding creep.
