First Claim
1. An antitheft device for cases for digital versatile discs and the like, the case (1) being of the general type formed by a box and a lid or by two semi-boxes (2A, 2B), both being square in plan view, having three free sides and being hingedly connected on the respective fourth side which forms a spine (3), in such a way that, when the case is closed, it has the general form of a book, comprising spring closing means (11), one or more hubs (4), provided with retaining tabs (5A, 5B) and disc centering means (6A, 6B) formed by concentric circular sector segments, wherein the distance (H) from the inner surface (13) of the case (1) having the hub (4) and the upper surface (14) of the centering means (6A, 6B) is greater than the distance (h) between said inner surface (13) of the case and the upper surface (15) of the retaining tabs (5A, 5B).

Abstract
The invention discloses an anti-theft device for digital versatile discs and the like and consists of providing the hubs of the case with means guaranteeing that the discs may not be removed by pressure on the major outer surfaces of the case. This object is attained by modifying the structure of said hub in such a way that, when pressure is exerted on said major outer surfaces of the case, the centering means impinge against the opposite inner surface of the case and prevent the retaining tabs from flexing and releasing the disc from the retained position thereof. The invention is applicable to increase security against the theft of digital versatile discs and the like.
