  • Patent number: 5349331
    Abstract: A holder (10) exhibits a frame-like housing (11) having a base (12) for receiving a CD case (14). This case is inserted in the arrow directions (15, 16, 17). A closing element (13) is then pressed down in the arrow direction (18), whereupon it snaps in place. The CD case (14) is held by retaining wall parts (24, 25) disposed on the otherwise open housing-topside. For opening, a device having a vacuum source has to be attached to a connecting socket (28) in order for the closing element (13) to be re-released. The holder (10) is equipped with a signalling means, which, upon the passage of a contactless-working electronic barrier, triggers a signal if the holder containing the CD case were to be stolen.
