Abstract
An attachment device for a security or antipilferage tag, and a combination of such a device with the tag. The attachment device comprises a cap having an upper surface and a lower surface, and a pair of electrically conductive pins depending from the lower surface, and an electrical conductor within the body of said cap which makes an electrical connection between the pair of pins. The tag forming one element of the combined tag and attachment device includes a first opening adapted to receive one of the pins and to permit electrical contact between the one pin and a first part of the electrical circuit within the tag, and a second opening adapted to receive the other of the pair of pins and to permit electrical contact between the other pin and a further part of the electrical circuit within the tag. Unauthorised removal of the attachment device from the tag results in the generation of an alarm signal.
