A hoop member is connected to the cap and includes a plurality of extensions that are biased by at least one resilient member connected to the cap so as to press against the inner Periphery of the tubular body. The extensions are connected to a drive handle mounted underneath a bail of the cap and cooperate with the at least one resilient member.
