Abstract: An anti-theft device for securing an article of merchandise against unauthorized removal from a display counter. The anti-theft device includes two pairs of arms slidingly disposed within the housing. Grips are disposed on distal ends of the arms and are configured to receive and secure edges of an article of merchandise. A locking mechanism is disposed within the housing of the anti-theft device. Complimentary gear teeth are disposed on the outer surface of the locking component and the inner edges of the arms. An actuator transitions the locking components between a first unlocked configuration in which the gear teeth of the locking components are retracted away from the gear teeth of the arms, and a second locked configuration in which the gear teeth of the locking components engage the gear teeth of the arms.

The anti-theft device includes two pairs of arms slidingly disposed within the housing. Grips are disposed on distal ends of the arms and are configured to receive and secure edges of an article of merchandise. A locking mechanism is disposed within the housing of the anti-theft device. The locking mechanism includes two locking components in a sliding configuration with respect to one another. Complimentary gear teeth are disposed on the outer edges of the locking component and the inner edges of the arms. An actuator transitions the locking components between a first unlocked configuration in which the gear teeth of the locking components are retracted away from the gear teeth of the arms, and a second locked configuration in which the gear teeth of the locking components engage the gear teeth of the arms.

Abstract: An anti-theft device for securing an article of merchandise against unauthorized removal from a display counter. A clip securely holds the article of merchandise. The clip has a hook on a bottom surface thereof. A base has an aperture configured to receive the hook. When the hook is inserted into the base through the opening, the clip is shifted relative to the base such that the point of the hook resides underneath a top plate of the base. A locking member immobilizes the clip within the base preventing the hook from becoming realigned with the base. A key is used to retract the locking member to release the clip from the base.
