摘要： A yarn draw-off pipe for drawing off a yarn from an open-end spinning device. The draw-off pipe is equipped with first and second pipe sections, which are connected to each other through a connecting piece. The connecting piece contains a chamber and is provided with a deflection surface extending into the chamber. The latter is part of an insert. The connecting piece is provided with an insertion opening for this insert on its side towards the spinning element, when assembled, the insert is secured axially between the front end of the insertion opening and the first pipe section or, alternatively, between the two pipe sections. The insert is made of a ceramic material and, with its end towards the spinning device, projects radially beyond the outside diameter of the first pipe section. The area of the guide left free by the insert is filled with a plastic material.
