Abstract: This invention is a tamper-resistant enclosure for a coin-operated vending apparatus and the like wherein the locking device is fixedly attached to and mounted internally of the enclosure making it less vulnerable to theft and vandalism. The locking mechanism includes a ring-shaped hanging lock that is attached by weldment to an interior end wall of the enclosure. The lock is positioned in substantial alignment with an aperture in the front end wall to permit operation of the lock from the exterior of the enclosure by a key. The top cover includes an integrally formed locking flange which passes through a slotted opening in the end wall adjacent the lock such that the lock is positioned in an operative relationship with an aperture in the locking flange when the slideable top is in a closed position enabling the enclosure to be secured. The enclosure is adaptable to use for vending any suitable consumer product or to any application where a secure, corrosion-resistant enclosure is desired.
