Abstract
Abstract A noise suppression apparatus for use with a spring. The apparatus includes a plurality of circular tubular members having a longitudinal slit in the tube wall and a radial slit. The slits allow the tubular members to be separated and disposed about the spring. Each of said circular tubes is interconnected by a web member. When the apparatus is snapped around the spring and the spring is compressed, any noise resulting from metal to metal contact will be suppressed by the apparatus.
