Abstract
An elongated strip-type body member of spiral configuration decreasing in radius of curvature toward one end thereof is provided. The strip member is of greater width than thickness and includes a generally outwardly projecting terminal end on its greater radius of curvature end extending generally axially of the spiral of the strip member. The body is constructed of resilient shape retentive, but flexible material. One longitudinal edge of the strip member comprises the inner periphery of the spiral and the other longitudinal edge of the strip member comprises the outer periphery of the spiral. The aforementioned one inner longitudinal edge of the strip is of greater thickness than the other outer longitudinal edge and the strip member tapers in thickness from the greater thickness longitudinal edge toward the lesser thickness longitudinal edge.
