A separating device for tubes (2) which are advanced and turned using the pilger step-by-step method has a satellite carriage (6) with a tube clamping arrangement (19) as well as a separating element (18). The satellite carriage (6) is supported axially resiliently in relation to a main carriage (7) supporting the motor (15) of the separating device, the advance of the main carriage (7) being controlled by a distance measuring device which takes in the distance between the satellite carriage (6) and the main carriage (7). <IMAGE>
