ABSTRACT:
The coupling device 1 serves to connect a reservoir 3 to a machine, for instance for use in agriculture in the spraying of herbicides. In order to prevent personnel coming into contact with the concentrated herbicidal substance during changing of the reservoir the line 8, which draws the substance out of the reservoir 3, can be retracted inside the coupling element 4 and the flexible casing 13 connecting thereto. Prior to changing of reservoir 3 the line 8 is entirely retracted into the coupling piece 4 and casing 13, thereby sealing with a suction inlet 9 against the inner bore of coupling piece 4. Dripping liquid therefore remains contained by the coupling piece 4 and the casing 13.
