Abstract
There is disclosed a tag for use in an electronic article surveillance system including a housing, a detectable marker held by the housing, and a releasable magnetic lock. The lock, which cannot be defeated by deflecting the housing, securely grips a pin by means of opposed jaws. The jaws and a pair of leaf springs are constructed of a single piece of sheet metal. Magnetic biasing of the sheet metal overcomes the forces exerted by the springs and causes the jaws to open to release the pin.
