A cap (30) is removeably secured to the upper portion of the shank (16) and has interior walls forming an expansion chamber (34) with a slotted bottom wall. The upper portion of the shank (16) is provided with exterior longitudinal channels (29) which extend below the bottom of the cap so that the expansion chamber may communicate with the atmosphere.
