ABSTRACT:
A tamper-proof device is provided for lockingly attaching a piece of equipment such as a TV set or a microwave oven to a support base. It has a pair of rigid plates that are respectively connected to the piece of equipment and the support base. One of the plates is surrounded by a flange which defines a closed area in which wedges are located to hook both plates together. The two plates are rigidly connected to each other by a screwable bolt that can be reached with a screw driver through a coaxial opening provided in the flange. A sleeve extends in between the head of the bolt and the opening. This sleeve can be closed by key-operated lock in order to prevent access to the bolt. The lock is free to rotate within the sleeve even when its latch is locked in outward position. Such prevents a theft from breaking the latch by forcing the lock into rotation in a cantilever fashion. A resilient plate is mounted within the closed area in such a manner as to extend radially close to the sleeve in order to contact the latch when the latch projects radially outwardly of the sleeve. This plate is resilient enough to let the latch flip over it if too much rotational force is applied to the lock within the sleeve.
