Abstract: A quick-release clamp assembly for a weightlifting bar has first and second clamp members connected together by a pivot connection for rotation about a pivot axis. The first and second members are movable about the pivot axis between an open position in which the clamp assembly can be placed on and removed from the weightlifting bar, and a closed position in which the clamp assembly is clamped securely onto the weightlifting bar. The first clamp member has first and second resilient bar engaging structures spaced from the pivot axis. An adjustable third bar engaging structure projects inwardly from the second clamp member adjacent to the pivot axis. The third bar engaging structure is arranged to engage an outer surface of the weightlifting bar and to move to an over-center locking condition when the first and second clamp members move from their open position to their closed position.
