A locking device for a merchandise display hook has an upper rod disposed along a longitudinal axis and a lower rod disposed generally parallel to the longitudinal axis and the upper rod. The locking device includes a housing having a vertical slot adapted to receive the upper rod and the lower rod of the display hook. A bayonet is movable between a locked position in which a portion of the bayonet extends into the slot and restricts movement of at least one of the upper rod and the lower rod within the slot, and an unlocked position in which the bayonet does not extend into the slot and thereby permits movement of the upper rod and the lower rod within the slot. An elongate nose depending outwardly from the housing defines a channel that intersects the slot of the housing and receives the upper rod of the display hook with the upper rod and the lower rod disposed within the slot.

A reversible locking device according to claim 1, wherein the housing defines a second slot and wherein the at least one of the upper rod and the lower rod is passed through the second slot with the lock in the unlocked position to remove the housing from the at least one of the upper rod and the lower rod. 5. A reversible locking device according to claim 4, wherein the lock comprises a bayonet that blocks access to the second slot in the locked position and permits access to the second slot in the unlocked position. 6. A reversible locking device according to claim 5, wherein the bayonet is biased by a biasing force towards the unlocked position. 7. A reversible locking device according to claim 5, wherein the lock further comprises a shuttle that engages the bayonet for retaining the bayonet in the locked position. 8. A reversible locking device according to claim 7, wherein the shuttle is biased by a biasing force towards the bayonet. 9. A reversible locking device according to claim 8, wherein the shuttle is made of a magnetically attractable material and further including a key comprising a magnet that attracts the shuttle against the biasing force away from the bayonet. 10. In combination: a merchandise display hook having an upper rod defining a longitudinal axis and a lower rod disposed generally parallel to the longitudinal axis of the upper rod; anda reversible locking device comprising: a housing having a first slot formed therethrough adapted to receive the upper rod and the lower rod of the merchandise display hook therein;a bayonet disposed at least partially within the housing, the bayonet being movable between a locked position in which at least a portion of the bayonet extends into the first slot and thereby restricts movement of at least one of the upper rod and the lower rod within the slot, and an unlocked position in which the bayonet does not extend into the first slot and thereby permits movement of the upper rod and the lower rod within the first slot; anda nose depending outwardly from the housing in the direction of the longitudinal axis defined by the upper rod, the nose defining a channel that intersects the first slot of the housing, the channel being adapted to receive the upper rod of the merchandise display hook with the upper rod and the lower rod disposed within the first slot of the housing. 11. The combination according to claim 10, wherein the nose comprises: an upper portion depending outwardly from the housing in the direction of the longitudinal axis defined by the upper rod; anda lower portion depending outwardly from the bayonet in the direction of the longitudinal axis defined by the upper rod, the lower portion slidably engaging the upper portion in the locked position with the upper rod disposed between the upper portion and the lower portion. 12. The combination according to claim 11, further comprising: a shuttle disposed within the housing, the shuttle being movable between an engaging position in which the shuttle engages the bayonet and thereby prevents movement of the bayonet from the locked position, and a disengaging position in which the shuttle does not engage the bayonet and thereby permits the bayonet to move from the locked position to the unlocked position. 13. The combination according to claim 12, wherein the shuttle is biased towards the engaging position and wherein the bayonet is biased towards the unlocked position. 14. The combination according to claim 13, wherein the shuttle is made of a magnetically attractable material and further including a key comprising a magnet that attracts the shuttle from the engaging position in which the bayonet is retained in the locked position to the disengaging position in which the bayonet is released from the locked position and biased towards the unlocked position. 15. The combination according to claim 14, wherein the housing has a recess formed therein having a predetermined shape and wherein the magnet of the key has a complementary shape for being received within the recess. 16. The combination according to claim 10, wherein the nose is reversible in the direction of the longitudinal axis defined by the upper rod so that the reversible locking device is in a first orientation on a first type of the merchandise display hook and in a second orientation on a second type of the merchandise display hook. 17.
