A B S T R A C T A device is disclosed for use in connection with tapping off fluid from or filling fluid into a container through an internally threaded tapping or filling hole provided in a wall of the container and adapted to be closed by means of an externally threaded generally cup-shaped plug having an outwardly open cavity in which an implement may be inserted for rotating the plug. Said device comprises a bell-like housing which is adapted to be removably mounted with an open end thereof over said tapping or filling hole and which is provided with an opening through which fluid may be fed into or discharged from the housing, and a tool for manually operating the plug from a position outside the housing. Said tool comprises a shaft which extends slidably and rotatably through a portion of the housing opposite to the open end of the housing, handle means provided at an outer end of said shaft, and plug holding means provided at an inner end of said shaft. Said plug holding means comprises expansion means insertable into said cavity in the plug, a carrier for said expansion means, said carrier being mounted on the tool shaft, and actuating means for the expansion means. Said actuating means are operative to expand the expansion means into frictional contact under pressure with the side wall of the cavity in the plug. The carrier for the expansion means is mounted for limited movement on an inner end portion of the tool shaft, while the actuating means for the expansion means are rigidly connected to the tool shaft.
