Zusammenfassung:A lead terminal can be introduced through the case cover (4) of accumulator cells. To this end, a union nut (6) is screwed onto the shaft of the lead terminal at the level of the cell cover. The lower end of the union nut (6) has an extension with a throat (6'') which receives a sealing O-ring (3) and presses the latter against an axial shoulder (1') of the terminal shaft. Said throat engages with the sealing O-ring by means of a pressure surface which is inclined at a predetermined angle to the axial direction and which can also press the sealing O-ring axially against the terminal shaft. The union nut is sealed radially against an axial sealing surface of a collar (4''') of the cell cover by another annular seal (5). The outside of said collar forms an axial sealing surface for a sealing lip (8) of the covering cap (7) which is axially mobile relative to said sealing surface.
