ABSTRACT:
Spring retaining clips formed of spring wire firmly hold a screen deck to a plurality of mounting bars on a vibrator. The clips each have facing, semi-circular upper and lower end portions connected on one side to slightly angled connecting portions which are joined by a central loop portion. As a clip is mounted over a support rod on the bottom of a screen deck and under a mounting bar on the vibrator, its ends are forced apart causing the angled connecting portions to become vertical as they move toward contact with a vertical side portion of the mounting bar. Additional separating forces applied between the ends of the clip during vibration of the screen deck after the connecting portions have become vertical are strongly resisted by the ever increasing force exerted by the central loop portion which must assume a smaller diameter as the end portions move apart.
