Abstract: An adjustable tie-down stretch cord comprising an elastic rope and a pair of slidably-mounted hooks. The hooks have a cylindrical tubular member and an S-shaped hook member. The tubular member is provided with a specially-shaped bore and flared slot in the wall. The inner bore at a throat end has a diameter slightly larger than the diameter of the elastic rope and increases to a flared end. The flared slot extends from near the throat end to the flared end, increasing in width in a curved manner. The hook member has a hook portion and a rib portion. The elastic rope is formed of a plurality of elastic strands or sheets wrapped in a woven or braided, polypropylene, nylon, polyester, or cotton jacket. The hooks are retained on the rope by knobs formed by folding over and crimping each end of the rope using a hog ring.
