This invention consists, on the one hand, of a reception unit, and, on the other hand, of break-in detectors consisting of a monitoring system exchanging information by a radiofrequency link with the reception unit, in cyclic transmission, and thus working in positive safety. The detector consisting of a housing (1) is fixed onto the container (7) by means of a safety cable (3) and of a magnetic fixing (2). The electrical safety loop (5) will loop round the closure system of the container (8) in such a way that opening the door (9) of this container inevitably entails opening the electrical circuit represented by this safety loop (5), thereby triggering an alarm. Moreover, if the container is moved beyond the limit of transmission, the alarm will be triggered. <IMAGE>
