Abstract
A housing with a retaining device is arranged on a base plate and comprises clamping studs which are arranged in a circle, which are radially resilient, and which have clamping surfaces facing radially outwards for gripping into a central opening of at least one disc-shaped information carrier, for example a CD. To avoid a destruction of the clamping elements in the case of impacts, rigid support studs with support surfaces facing radially outwards are provided between the clamping studs, and the diameter of the support surfaces arranged in a circle is somewhat smaller than the diameter of the central opening of the information carrier.
