A security package having a slidable locking structure to retain a CD, cassette or the like in the security package. The slidable locking structure has a stationary surface which contains a T-shaped protrusions each having a lever arm. A slide plate contains recesses for receiving each end of the lever arm, apertures adjacent to these recesses and a lip along an edge. The security package is locked when the slide plate is slid to engage the lever arms into the recesses allowing the lip to extend over the holding structure to retain the CD, cassette or the like. A key which mates with the apertures is used to apply a simultaneous uniform force to release the lever arms from the recesses.
