Since the narrow side of the claw-like holding device can only be recognized very poorly or not at all from the outside of the housing, unauthorized manipulation with tools not specifically provided for this purpose, which must also be moved on a path that is not immediately recognizable, is largely ruled out.
  • the claw-like holding device can permanently destroy one or more of the positioning elements during the displacement due to the action of the tool and thus reach an open position in which the mandrel is released and can be pulled out of the housing.
  • This destruction of the positioning elements clears the way for the displacement of the claw-like holding device without the need for complex guide mechanisms or limitations for the path when the claw-like holding device is displaced. If it is ensured that, with the exception of the positioning elements on the way of the displacement of the claw-like holding device, no housing parts interfere, the claw-like holding device can be safely moved out of the area in which it interacts with the mandrel.

This ensures a safe movement of the claw-like holding device during the process of opening the claw-like holding device, whereby the detachment of the claw-like holding device from the mandrel can always be ensured by the displacement of the claw-like holding device under the action of the force of the tool. Due to the linear guidance of the claw-like holding device, tilting or tilting of the claw-like holding device during the opening movement is almost impossible, since the linear guides ensure reliable support of the forces exerted by the tool on the claw-like holding device.

Abstract

L’invention concerne un dispositif de protection de marchandise (1) qui comprend un boîtier (2, 21) dans ou sur lequel est placé un élément de protection de marchandise détectable, ainsi qu'un moyen de fixation en au moins deux parties qui sert à fixer le boîtier (2, 21) de manière détachable sur une marchandise ou un article similaire. Le moyen de fixation (7, 7’, 8) comprend une broche (8) qui peut être attachée à la marchandise, qui présente une tête plus épaisse (9) et dont la pointe (24) opposée à la tête (9) peut être insérée à travers une ouverture (25) dans l'intérieur du boîtier (2, 21) et, une fois à l'intérieur du boîtier (2, 21), peut être fixée au boîtier (2, 21) au moyen d'un dispositif de retenue (7, 7’) en forme de griffe formant l’autre partie du moyen de fixation (7, 7’, 8). Un outil (5) peut être introduit de l'extérieur du boîtier (2, 21) dans l’intérieur du boîtier (2, 21), de manière à déplacer des parties du moyen de fixation (7, 7’, 8) d'une position de verrouillage (7) dans une position d’ouverture (7’). A cet effet, le dispositif de retenue en forme de griffe (7, 7’) peut être déplacé par rapport à la broche (8) et par rapport à sa position initiale au moyen de l’outil (5), ce qui libère la liaison existante entre le dispositif de retenue en forme de griffe (7, 7’) et la broche (8).
