Abstract

An exterior surface has a vertical mid-plane and a horizontal aperture there through. An annular recess is provided at the vertical mid-plane. The exterior surface has planar end faces parallel with each other. The horizontal aperture has opposed frusto-conical surfaces with a central axis. The frusto-conical surfaces have interior edges at the vertical mid-plane and exterior edges at the planar end faces. The exterior edges are larger than the interior edges. Coupling grooves extend to opposite sides of the recess. The coupling grooves have a generally semi-circular configuration. The grooves are parallel with each other at an angle with respect to the central axis. The grooves have midpoints spanning the central axis. The coupling grooves are adapted to receive separated strands of draw string.
