FIELD: physics.SUBSTANCE: label for electronic surveillance of separate articles consists of a housing, a swivel clamp and an arched channel. The swivel clamp is connected to a housing for clamping a removable pin for detachable connection of the pin to the article. The arched channel lies in the housing; one end of the channel opens onto the side surface of the housing and the opposite end of the arched channel lies next to the swivel clamp. The arched channel has a key groove formed on a section of the arched channel. The key groove has an L shape which enables to inert a hook into the arched channel to control the swivel clamp. The L shape of the key groove further essentially prevents entrance of the formed wire into the arched channel in order to control the swivel clamp. The arched channel has a length which is measured between ends of the arched channel, and the L shaped key groove further includes a vertical section and a horizontal section. The vertical section and the horizontal section lie at different distances along the length of the arched channel.EFFECT: preventing falsification and activation of the disconnection mechanism using other instruments other than those intended for that purpose.10 cl, 14 dwg |
