  • Patent number: 5577299
    Abstract: A quick-release mechanical knot device for use in securing objects together having a novel means for quickly and safely releasing the mechanical knot device from the body of a rope or tether regardless of the amount of tension or load strain acting on the rope. The device comprises a semi-rigid elongated stock member having at least two circular orifices formed at opposing ends of a curvilinear intermediate portion. The first and second orifices are substantially perpendicular to the linear length of the stock member and formed with a substantially parallel and concentric axis to one another. A leading end of a rope is inserted through the first and second circular orifices of the stock member and wrapped around a stationary or movable object to form a hitch. The leading end of the rope is then placed between the curvilinear intermediate portion of the stock member and the portion of the rope passing between the first and second orifices to form a capture for the portion of the rope therebetween.
