ABSTRACT:
A quick release collar for a weight lifting barbell includes a collar body, an axially movable sleeve and a plurality of radially movable balls which are cammed into frictional engagement with the bar. A tension ring rigidly attached to the sleeve has a tapered inner surface portion which controls the radial positions of the movable balls. A coil spring biases the sleeve and tension ring toward a locked position in which the movable balls securely engage the bar. The collar is easily unlocked with one hand so that it can be slipped off the bar.
