摘要

The apparatus has security units (2) arranged in a base (1), and a detecting unit triggering an alarm based on the detection of an intrusion of the apparatus. A trim plate is fixed to the base in a removable manner, for adapting an assembled/disassembled configurations and preventing the disassembling of a cover (3) and an access to the units, in its assembled configuration. The detecting unit has a motion detector (5) detecting the movement of the plate from assembled configuration to disassembled configuration, and a partial elastic control unit (51) that is in the form of spring wire.
