<p>In the device for securing a compact disc CD (1) against theft, the disc CD is housed into a cassette comprising a support (3) presenting a plurality of elastic support tongues (5) curved through a central opening (2) of the compact disc (1) and pressure bearing against the edge of the opening. The ends of the tongues are folded in a plane parallel to the disc plane and radially directed inwardly. Above the disc on the tongues there is arranged a cover plate (7) which carries or at least covers partially a signal emitter circuit operated with a detector such as an electronic safety circuit or a magnetic tape or coding. Said cover plate (7) is locked or lockable to the support (3) by means of a movable and/or elastically deformable safety member (13) removably engaged under at least one tongue (5) in mesh with the cover plate, the safety member (13) being comprised particularly of an elastic ring (14) or another catch element.</p> |
