In an open-end rotor spinning device having a rotatable spinning rotor and a coaxial yarn withdrawal navel mounted in a rotor cover, a tubular twist choking member is removably mounted rotatably in general airtight relation to the cover at an angle with respect to the rotor axis with a yarn withdrawal tube affixed coaxially to the twist choking member. A curved passageway extends longitudinally through the twist choking member with plural obliquely-arranged yarn deflection elements constricting the convex side of the passageway. The twist choking member and the yarn withdrawal tube may be selectivey positioned rotatably as a unit to achieve a desired effect on spinning stability and yarn quality.
