ABSTRACT:
The present invention relates to an arrangement for sealing a storage battery casing having at least one opening in the lid or cover (5) thereof, with the aid of a sealing plug (2) provided for each opening and retained in a sleeve-like fitting (1) surrounding the opening. The invention is characterized in that the sealing plug (2) includes a substantially sleeve-like outer plug part (3) and an inner plug part (4) arranged to be inserted axially into the outer plug part (3). The outer plug part (3) has a radially expandable portion intended for accommodation in the fitting (1), and the inner plug part (4) forms an expander means which, when inserted axially into the outer plug part (3), expands the expandable portion from a radially compressed state, in which the portion can be moved axially in the associated fitting (1), to a radially expanded state, in which the outer plug part (3) is retained in the sleeve-like fitting (1) by engagement of the expandable portion with the radially inwardly facing surface of the fitting.
