I claim:

l. In a device comprising two wires and an interposed twisted wire cable in juxtaposition in a common plane, and a clip surrounding said juxtaposed wires and cable and indented at a point centrally of its length upon the, cable, said indentingy being of sufficient depth to flatten saidv cable and to spread the same laterally into frictional holding engagement with said Wires, and

said cable being of smaller diameterthan said wires whereby freedom of movement of said cable Within the ends of said clip at right angles to said plane will be permitted. Y

2. In a device comprising three elements inA in frictional-wed'ging engagement with said por-A in the principles of this invention and the scope I tional holding engagement With said wires, and said cable being of smaller diameter than said wires, the Wall of the clip in which the indentation is formed being of an arcuate form with its center on the same side of the clip as the indentation.

3. In a. spring cushion comprising parallel rows y of helical wire springs, cable ,ties interposed between adjacent portions of the terminal convolutions of adjacent springs of adjacent rows, said ties being of shorter diameter than the diameter of the wire stock from which the springs are formed, and clips surrounding said ties and said portions of said springs and secured to said ties and saidjportions of said springs by indentations impressed 'in the portions of the clips overlying the outer faces of said ties, producing projections tions of said springs and in compression engagement with said ties, flattening and spreading said ties into frictional engagementwith said portionsof said springs.
