Abstract (en)
[origin: EP0433609A1] The invention relates to a plug coupling for the pivotable connection nozzle of vacuum cleaner accessories for connection to the suction nozzle of the vacuum cleaner. This takes place by a locking knob in the connection nozzle which projects into a locking opening in the suction nozzle. The locking knob is actuated by a pushbutton which, when the connection is pivoted, automatically moves into the vertical plane and slightly beyond against a run-up surface and is thus pressed in. The connection can be released by this means. <IMAGE>
