The use of soft material or thinly designed tongues is made possible for fastening devices for at least one disc shaped data carrier with a central opening in a cassette, wherein the cassette comprises a middle part on which a crown of tongues is provided, elastically insertable into the central opening of the at least one data carrier, while still preventing unwanted falling out of the data carrier, for example CDs or DVDs. This is made possible in that at least one connecting element is provided, moveably connecting at least two of the tongues, wherein the connecting element is produced in the production of the fastening device in a first position and wherein after the production for increasing the restoring force of the tongues against the data carrier the connecting element is moved into a second position.
