ABSTRACT:
A pair of opposed arms extend in spaced parallel arrangement to each other, each of which arms include relatively short handle portions and relatively long gripping portions. The inner or opposed gripping edge of each arm includes a plurality of jagged teeth formed by relatively deep notches in the opposed edges of the arms. The teeth and notches are provided throughout substantially the entire gripping portion. The notches extend into the surface of the arms a distance of at least one-half inch. The arms are joined together by a connection about a pivot point positioned intermediate the handle portion and the gripping portion. A compression spring extends between the handle portions for normally biasing the gripping portions toward a closed position. One of the handles of the device receives one end of a tether which is attached at the other end to the boat. The extreme upper end of the gripping portion is provided with a beveled surface so that as the device is pushed into underbrush or undergrowth or onto a small branch, the arms are caused to spread, then clamps on the underbrush or undergrowth, whereupon the teeth grip the undergrowth tightly and provide a secure mooring for the boat.
