Abstract

Externally threaded opposite end portions of the bar of a barbell are insertable into the central apertures of cylindrical weights. Locking sleeves having manually retractable inward-projecting locking pins are fittable on the externally threaded bar end portions. With a locking pin in its projected position, the locking sleeve can be rotated like a conventional nut so as to advance toward or away from the weights. With the locking pin held in a retracted position, the locking sleeve can slide longitudinally in either direction along the threaded bar end portion without rotating.
