An anti-theft device comprised of a housing hingably connected to a cover. The housing and cover can move from an open position to a closed position to clasp and secure an article to be monitored. The housing and cover have latch components. When the housing and cover are rotated to a closed position in relation to one another, a latch component on the cover interconnects with a latch component of the housing to hold the housing and cover in a closed position. The latch components may be releasably lockable and may be released by application of a magnet to a blocking component in the housing which has a magnetically-attractable element associated with it, combined with manual manipulation of a latch switch to disengage the latching components of the housing and cover. The anti-theft device carries at least a passive electronic article surveillance element. More advanced electronic article surveillance elements may also be carried in the housing.

1. An anti-theft device comprising; a first component hingably connected to a second component, said first and second components rotatable along a hinge axis between open and closed positions and, when in said closed position, defining a passageway for receiving a portion of an object to be monitored;said first component comprising a latch, a first spring, and a housing defining an internal compartment, said latch including a first interlock element;said second component comprising a latch receiver for receiving said latch when said first and second components are rotated to said closed position and said latch is moved to a latched position;electronics located within said internal compartment;a blocking component comprised of a second interlock element; and,a second spring;said second spring moving said blocking component into a blocking position to prevent a return of said latch when said first component and said second component are rotated to said closed position and said latch is moved to said latched position;said first spring biasing said latch in said latched position toward said blocking component to interlock said first interlock element with said second interlock element. 2. The anti-theft device of claim 1, wherein: said blocking component is at least partially comprised of a magnetically attractable material and can be retracted to a non-blocking position when specific conditions are met;said specific conditions comprising the manipulation of said latch against said first spring to disengage said first interlock element from said second interlock element, and the application of a magnet to said anti-theft tag to overcome said second spring. 3. The anti-theft device of claim 2, wherein: when said blocking component is retracted to said non-blocking position, and said manipulation of said latch is ceased, said first spring moves said latch into an unlatched position. 4. The anti-theft device of claim 3, wherein: when said latch is in said unlatched position, said latch maintains said blocking component in said non-blocking position. 5. The anti-theft device of claim 1, wherein: said electronics comprise a passive electronic article surveillance element. 6. The anti-theft device of claim 1, wherein: said first component further comprises a switch aperture passing from said internal compartment to external of said housing;said electronics comprise a circuit board, microprocessor, battery, audible alarm generator, and a closure switch;said closure switch extending through said switch aperture in said housing;said second component changing the state of said closure switch when said first and second components are moved to said closed position. 7. The anti-theft device of claim 6, wherein; said electronics further comprise communication elements. 8. The anti-theft device of claim 6, wherein; said electronics further comprise infrared communication elements. 9. The anti-theft device of claim 6, wherein; said electronics further comprise radio frequency circuitry elements. 10. The anti-theft device of claim 6, wherein; said electronics further comprise a latch switch. 11. The anti-theft device of claim 1, further comprising; a hanger aperture for hanging said anti-theft tag and said object to be monitored. 12. The anti-theft device of claim 11, further comprising; a first connector element;a hanger member, said hanger member comprising said hanger aperture and a second connector element;said first connector element connecting to said second connector element.
