A tapered slot can be formed in the body below the opening. A width of the tapered slot proximate the opening can be greater than the width of the tapered slot distal the opening. The tapered slot can be adapted to receive a tapered wedge and expand radially outward as the tapered wedge slides within the tapered slot and away from the opening.
