1. A thread draw-off nozzle for an open-end spinning device, comprising:
a thread-guiding surface which extends between an entry opening and a draw-off opening and which tapers in a shape of a funnel toward the draw-off opening; and
a blocking element which protrudes from the thread-guiding surface and which has a thread stop surface designed such that the thread stop surface blocks a thread to prevent the thread from passing over the thread stop surface and circulating over the thread-guiding surface.
