<p>The invention refers to a device, the purpose of which is to prevent theft from stores by rendering the stolen object unusable for the thief. The inventor solves the problem by way of a radio loop (11) transmitting a directed and coded signal (10) which in turn is received by a receiver (9) in the device (14). The receiver (9) decodes the signal (10) and transforms it to a start impulse (15) for the release mechanism (7) in the device (14). Hereby the glass/plastic ampoule (6) is destroyed and its content, a fluid, spreads under pressure through the holes (16) in the device (14) and renders the theft-protected item (3) unusable.</p> |
