Abstract

A device for transferring a signal has two end points (6, 8) between which a conductor (10) extends in spiral turns and is arranged within a substantially circular cassette (K). The cassette (K) consists of two parts, a rotor (11) which is turnable about its axis and a stationary stator (12) which surrounds the circumference of the rotor and encloses the conductor (10). On the rotor (11) there is an outward protruding extension (15) for receiving a screw (16) which is displaceable in the axial direction of the cassette (K), and serves for a locking of rotor (11) and stator (12). There is also present on the rotor (11) a spring element (17) which is displaceable by means of a screw (16) and which, in mounting position of the cassette (K), is held firmly on the stator (12) and, in the working position of the cassette (K), is separated from the stator (12) by a space.
