Abstract
An alarm tag is provided having two parts, one of which has a pin attached thereto and extending through the part and into locking engagement with the other part. One part has means for activating an alarm device, the alarm device being either in the other part or an external alarm which interacts with the tag through an alarm field. Further, one part has a contact element operatively related to the other part such that disturbing the pin causes the contact to activate the alarm when the parts are separated.
