Date Sep. 4, 1980.A device for use in connection with tapping off fluid from or filling fluid into a container comprises a bell-like housing which is adapted to be removably mounted with an open end thereof over an internally threaded tapping or filling hole in a wall of the container 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 an externally threaded generally cup-shaped closing plug for said hole, 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. Said plug holding means comprises expansion means insertable into an outwardly open cavity in the plug, a carrier for said expansion means mounted on the tool shaft, and actuating means for the expansion means which are operative to expand the expansion means into frictional contact under pressure with the side wall of the cavity in the plug in order to improve and simplify the construction of the tool, the carrier is mounted for limited movement on an inner end portion of the tool shaft, while the actuating means are rigidly connected to the tool shaft.
