Abstract
An open-end spinning device comprises a spinning rotor rotating in a vacuum-loaded rotor housing which can be closed by a conduit plate having a receptacle receiving a replaceable conduit-plate adapter and a locking device, e.g., a bar spring, for spring-biasing the conduit-plate adapter into the receptacle. A blocking device comprising a hood-like cover is associated with the locking device for movement into an operating position only when the locking device is positioned in a locking position in which it reliably fixes the conduit-plate adapter.
