Abrégé

A detection device comprises a data memory (REG) which is arranged in a housing (G). The detection device further comprises a control unit (KE) with a nonvolatile memory (MEM) in which at least one reference datum (RD) is stored. The control unit (KE) is designed to determine at least one test datum (PD) and to store this in the data memory (REG). The control unit (KE) is further designed to read and test the at least one test datum (PD) for the presence and/or absence of modification with respect to the reference datum (RD). The control unit (KE) is further designed to recognize an opening of the housing (G) when the at least one test datum (PD) which has been read is modified or is not present. The detection device further has a deletion unit (LE) which is designed to delete or modify the at least one test datum (PD) in the data memory (REG) upon the occurrence of an opening signal caused by the opening of the housing (G).
