In the preferred embodiment, the adjustable clasp (10) has an inlet (14) and a radial port (20) which are connected by a conduit. The inlet end (12) of the adjustable clasp (10) is narrower than the fastener end (16) of the adjustable clasp (10). A helical groove (24) is provided on the exterior (22) of the adjustable clasp (10) and extends from the radial port to an exterior bore (26) near the fastener end (16) of the adjustable clasp (10). The exterior bore (26) extends through the solid center core of the adjustable clasp (10) and is substantially perpendicular to the center axis of the adjustable clasp (10) and helical groove (24). |
