An open-end spinning device has a spinning rotor ( 2 ) with a rotor groove ( 25 ) at its greatest inside diameter in which fibers are collected. A yarn shank ( 27 ) extending from a yarn withdrawal nozzle to the rotor groove ( 25 ) is curved in the vicinity of the rotor groove ( 25 ) counter to the direction of rotor rotation during the spinning process forming a lagging tie-up zone whereat yarn formation takes place. A rotor insert ( 18 ) is rotatably supported within the spinning rotor coaxially to the rotor axis. The rotor insert ( 18 ) can be caused to rotate in a contactless manner by the rotation of the spinning rotor. The rotor insert ( 18 ) comprises a yarn guide conduit ( 20 ) that receives the yarn shank ( 27 ) to effect a retardation of the rotor insert ( 18 ) during normal spinning operation, which significantly improves the stability of the spinning process over known open-end spinning devices.
