Abstract: There is disclosed an improved tamper-proof hanger having interchangeable shoulder cups. The tamper proof hanger is provided with gripping arms which move in the vertical plane of the hanger to clamp down on the hanger arms. The shoulder cups attach to the ends of the gripping arms, and a garment is secured to the hanger by clamping it between the shoulder cups and hanger arms. A locking mechanism locks the gripping arms in the clamping position and locks the hanger to a rod to prevent theft. The shoulder cups have a U-shaped cross-section and may slide onto the ends of the gripping arms using a tongue and groove arrangement. They are lined on their underside with an anti-slip material. This material preferably consists of a rubber pad having a central band extending away from the bottom of the cup to leave a gap in between. In this way, the band may conform to the size of the shoulders of the garment being secured, so that the garment is best gripped and secured.

Abstract: A key-operable combination for use in a tamper-proof garment hanger, which combination is very simple yet efficient in structure and is capable of cooperation with a rack forming part of a garment gripping member for selectively holding the gripping member into and out of locking position. This key-operable combination comprises a cylinder lock comprising an outer lock cylinder solid with the larger casing and a key-operable rotary lock barrel mounted within the outer cylinder. An operating member is rotatably mounted on the outer lock cylinder, within the casing, this operating member and the lock barrel being coupled together for allowing rotation of the operating member when the lock barrel is key-operated into rotation. A pawl radially projects from the operating member. This pawl has a free end operatively engaging the rack of the gripping member.
