<p>A device for use in connection with tapping off fluid from or filling fluid into a container through a hole (13) closable by means of a threaded cup-shaped plug (17) comprises a housing (10), mountable over said hole (13), and a tool (30) for manually handling the plug (17), said tool comprising a plug holder (34), including two movable gripping jaws (37) having gripping portions (38), insertable into a cavity (18) in the plug (17) and by means of which the gripping jaws (37) may be brought into contact with opposite portions of the side wall (20) of the cavity (18). In order to make it possible to use the tool (30) for handling plugs (17) having cavities (18) of considerable varying diameter, the gripping portions (38) of the gripping jaws (37) are arranged to be moved from retracted inner end positions to expanded outer end positions through the action of spring forces applied from spring means (45) contained in the plug holder (34).</p> |
