Abstract: The present invention relates to a theft-deterrent device which is intended for attachment to theft-attractive articles and which includes a first element (1) which is provided with a connecting unit (5) that projects out from the first element. The connecting unit is intended to be inserted through the article to be protected. The article is locked to the device by attaching and locking the connecting unit to a second element (2). The first element includes a fragile marking substance container (6) which is broken or crushed when an attempt is made to release the elements from each other, so as to release a marking substance contained in the container and therewith render the article unusable. The first element includes a base element (4) which has the form of a one-piece structure and which includes a recess (7) having an opening through which the container (6) can be inserted into the recess.

Abstract: 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.

Abstract: The present invention relates to a release device for releasing theft deterrents from theft attractive goods. The release device includes a deterrent detaching element (2) having a release part (6) which is adapted to the theft deterrent concerned and which has a release function. The device also includes a mount (4), which is firmly secured to an underlying support surface. The theft detaching element (2) can be locked in the mount (4) in two alternative positions, of which one position enables activation of the release function, whereas the other position prevents activation of the release function.
