A ligature for retaining a reed on the mouthpiece of a woodwind instrument such as a clarinet or saxophone comprising a pair of rubber O-rings adapted to fit over the reed and mouthpiece applying sufficient compressive force to hold said reed in place. The O-rings are held at a predetermined fixed distance apart by the use of a stiff flat strip of braided nylon looped about each O-ring such as to allow for twisting and untwisting of the O-rings.
