Abstract
A method of fastening a line to an object to form a continually adjustable nonreturn knot to adjust the length and tension of the line. The line is passed from one side of an object to another through one or more holes in the object and one portion is tucked under another portion of itself, creating a nip, to pinch the one portion against a surface of the object. The friction added by the nip is sufficient to prevent the line from being pulled through the knot in one direction but is insufficient to prevent it from being pulled through in the opposite direction. In variations of the embodiments of the knot, a release line is also attached to the line proximate the nip to relieve the friction added by the nip sufficiently to allow the line to be pulled through the knot in either direction.
