A device for transmitting current between two terminals of a cassette (K) between which at least one ribbon cable is arranged that extends in turns. The cassette includes a fixed stator and a rotatable rotor between which the ribbon cable is positioned. One of the two terminals is movable relative to the other. The ribbon cable at its ends is located in the area of the terminals. It is brought out of the cassette at the terminals for the connection of continuing cables (17). At least two plate-shaped contact carriers (18, 19) are mounted to the outside of the stator of the cassette. The conductors of the ribbon cable on the one hand and the conductors of a continuing cable on the other hand can be connected to the contact carriers. The contact carriers are connected with one another by elastic snap-in elements to form a unit.
