Abstract
A safety rivet arrangement for indicating the unauthorized opening of a housing whose wall parts are connected with each other at a separating joint which has a covered outer edge. A safety rivet extends through the connection and is considerably harder than the material of the housing wall parts. The rivet ends are arranged recessed, and the safety rivet is also only loosely peened-over so as to be rotatable. By reason of its high material hardness, and the rotatable arrangement, the rivet cannot be drilled out with some evidence of the drilling.
