A winding device for winding up and unwinding a cable, tube or hose which comprises a cable, tube or hose section which can be wound on and unwound from the outer circumference, a cable, tube or hose section which is guided out of a hub and which does not turn with the rotatable drum and a spiral compensation length in the interstice between the rotating drum and the hub. The compensation length is supported on a supporting disc comprising an outer supporting ring which turns with the rotatable drum and an inner supporting disc between the outer supporting ring and the hub which does not turn with the rotatable drum. Furthermore, the hub is axially subdivided into two hub parts which can be displaced relative to each other and which can be firmly joined by means of a detachable locking device. When the locking device is open, a hub part linked with a turning spring can be turned relative to the hub part linked with the compensation length of the cable, tube or hose in order to pre-span the spring as desired. The two hub parts are then firmly interlocked by means of the locking device when the desired pre-tension has been set by the corresponding turning position.
