Abstract
A collar coacts with a chassis, sleeve and lever of a lockset to provide a retention and reinforcement system for lock assemblies. The collar has a flanged portion and a sleeve-engaging portion and is sandwiched between a lever and the cylinder. The sleeve-engaging portion includes at least one tab that engages the sleeve to retain the collar on the sleeve. Alternatively, the collar can be staked to the sleeve. A spring washer can be mounted between the collar and the chassis to take up variation in manufacturing tolerances. The result is a retention and reinforcement system that provides a protection against attack in the zone of attack around the handle-chassis interface.
