Abstract: A garment anti-theft device for captively receiving at least one clothes hanger of the type having a hook with a free distal end for receiving a support arm of a garment rack to suspend the hanger therefrom. The garment anti-theft device includes a body having at least one opening therein of a size large enough to receive a free distal end of a hook of a hanger introduced by movement of the hanger free end in a first direction into the opening. A cover is attached to the body for movement selectively between an open position and a securing position. The cover, in its position, allows the free distal end of the hanger to be directed in a first direction into the body opening so that the hanger is supported in an operative position on at least one of the support arm on a clothes rack and the body and out of the opening by movement of the free distal end of the hanger oppositely to the first direction.

Abstract: A security device for a garment display structure of the type having an elongate rail for supporting a garment/security hanger, with the elongate rail having a free end with a first cross-sectional area taken transversely of the length thereof. The security device has a blocking element removably attached in an operative position adjacent to the free end of an elongate rail on a garment display structure to thereby create an effective cross-sectional area, taken transversely of the length of the elongate rail, that is greater than the first cross-sectional area. With the inventive structure, the blocking element prohibits the passage of certain garments/security hangers, that encircle the elongate rail, over and past the free end of the elongate rail, that could otherwise occur in the absence of the blocking element on the elongate rail.
