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