Abstract: The invention relates to a connecting device (1) for transmitting electrical signals to and/or from a steering wheel (23) of a motor vehicle, having a positionally fixed component (2) for positionally fixed installation in the motor vehicle, having a hub part (3) which is rotatably mounted on the positionally fixed component (2) and which serves for connection to the steering wheel (23), and having a locking element (6) which is movably mounted on a bearing part (3) and which, during the connection of the hub part (3) to the steering wheel (23), is movable counter to a spring force of a spring element (14) from an installation position, in which a blocking bar (9) of the locking element (6) blocks the rotation of the hub part (3) relative to the positionally fixed component (2), into an operating position, in which the rotation of the hub part (3) is enabled, wherein the connecting device (1) has a plunger (18) which is mounted movably relative to the locking element (6) and which, during the connection of th

Abstract: The invention relates to an apparatus (2) for transmitting electrical signals to and/or from a rotatable component of a motor vehicle, having a positionally fixed stator (4) which is intended to be installed in a positionally fixed manner in the motor vehicle, and having a rotor (3) which is rotatably mounted on the stator (4) and which is intended to be coupled in a rotationally fixed manner to the rotatable component of the motor vehicle, wherein the stator (4) has a housing (5) in which a flat cable (14) for transmitting the electrical signals is arranged, wherein a connecting piece (6) which is electrically coupled to the flat cable (14) and is designed to be connected to a corresponding mating piece (15) of the rotatable component is arranged on the rotor (3), and wherein the rotor (3) has a viewing window (11) through which it is possible for a viewer looking from outside the housing (5) to identify a reference element (13) of the flat cable (14) in a neutral position of the rotor (3) with respect to th
