The anchor includes at least one fin mounted on, projecting outward from, and extending in an axial direction along the frustum-shaped body. The anchor also includes a flexible stiffener encircling a portion of the first opening. The anchor may also include strapping joined to and extending transversely and axially across the frustum-shaped body. The transversely extending strapping may interconnect a plurality of fins.
