A bend or hitch used on board ship to attach a rope to a ring or spar so that, by a pull on the rope, the hitch comes free. This is achieved by passing a bight of the rope under the other part so that when the strain is taken the bight is jammed. A pull on the end of the bight will clear it, and the bend is then dissolved. Hitches most often used in slippery form are sheet bends, clove hitches, and bowlines.
