Theft-deterrent device for use with theft-attractive articles

摘要

The present invention relates to a theft deterrent which is intended to be attached to theft-attractive articles and which is constructed for coaction with a release device adapted for the release of the theft deterrent. The theft deterrent includes a first element (10) having a connecting element (12) which projects out from the first element (10) and which is intended to be inserted through an article to be protected, and a second element (14) which can be attached to and locked on the connecting element (12). The second element (14) includes a casing (16) which houses a fragile marking-substance containing ampule (44) and a locking unit (18). The locking unit (18) is intended to receive and lock the elongated connecting element (12) and to be brought into engagement with the ampule when the connecting element is manipulated, so as to fracture the ampule and therewith release the marking-substance contained therein.
