ABSTRACT:
A flexible material such as garment fabric to be protected against theft is clamped into a lockable security tag. A key can be inserted into a key hole formed in the security tag for releasing the lock and to remove the tag from the garment item. The key thereby has a shape which complements a member of the cam mechanism so as to allow the cam to be operated with the key. A given decoupler is matched to a given batch of security tags, and the given decoupler is not matched to another, different batch of security tags. A certain store, therefore, has a matched decoupler for its tags while another store has a different decoupler which is matched to a different batch. The decoupler is preferably a key. The security tag is thereby provided with a number of pins or prongs which break or bend back if an incorrect key is inserted or if someone attempts to pick the lock.
