Abstract
A barbell collar includes a collar and sleeve arrangement that are telescopingly displaceable relative to one another to permit adjustment along a barbell support rod. Retractable detent spheres are mounted within the sleeve for engagement with annular grooves of the barbell to effect selective securement and positioning of the sleeve structure relative to the barbell rod.
