    • A recording and/or reproducing device. A cassette, which contains a magnetic tape and a coupling pin connected to the magnetic tape, can be loaded into the device. The device includes a pull-out element which can be coupled to the coupling element. The pull-out element can be held in order to be coupled to the coupling element with the aid of a retaining structure and is disengageable by the retaining structure after coupling. A latch is provided by which a disengagement of the pull-out element by the retaining structure can be inhibited or enabled, and the latch is constructed for cooperation with the coupling element. The latching is only enabled to disengage the pull-out element by the retaining structure when the coupling element is correctly coupled to the pull-out element.
