A metallic clip for holding the end bar of a sinuous cushion-supporting spring in position on the wooden rail of an article of furniture and having a horizontal base portion which seats on the top surface of the rail and a downturned flange which lies flush with the outside face of the rail, such flange having rail-penetrating anchor prongs which, when the clip is applied enters the wood transversely of the general plane of the wood grain, preferably at a right angle so as to inhibit splitting of the rail. The clip is formed from a flat metal blank by a punch press stamping operation in such a manner so that each prong is shorter than the width of the blank with the two prongs interfitting so that when they are bent out of the plane of the flange. Because the prongs are struck laterally from the vertical flange of the clip, they do not constitute added metal and therefore a considerably narrower continuous strip may be fed to the punch press in the production of successive clips, thus reducing the amount of metal required in the production of a given number of clips. |
