The disc member (16) is provided with a pair of openings (22, 24) on the disc periphery through which a fixed line length is threaded. The interior portion of the disc (16) is provided with at least two retainer clips (32, 34) having a hook shaped member (36) with an incline ramp surface (38) for cooperating with the portion of the line (26) extending between the two openings (22, 24). The line (26) is held in place by tension which causes the line (26) to travel down the ramp surface (38).</p> |
