Abstract
A T-handle lock assembly for vending machines or the like include a two-piece cylinder front handle and cylinder/extension rod housing subassembly which interlock by means of first and second asymmetrical flange edges integrally formed on the housing and corresponding recessed slots within the cylinder front handle. A single set screw is threaded into an aperture in the front handle extending in the direction of the slots to engage and rigidly secure the housing to the handle so that the lock cylinder is in alignment with a key access passage in the front surface of the cylinder front handle. The arrangement prevents access to the lock cylinder when in a locked condition even if the set screw is removed.
