Device for closing tubular plates of lead batteries has base member with pretensioned projections which when device is correctly positioned engage in tubes through detent catches

Closing device has a base member (5) with projections (3) which are pretensioned opposite the walls of the tubes and when the device is correctly positioned engage at the ends in the tubes. The closing device is fixed with the pretensioned projections and at least two adjoining projections have detent catches (13,14) which clamp with the walls. The projections can have a ring-shaped wall arranged on the base member whereby its side remote from the base member is closed by a head region (8) whose external contour corresponds to the internal cross section of the relevant tube. Die vorliegende Erfindung betrifft eine Vorrichtung zum Verschließen von Rohrplatten von Batterien, vorzugsweise Bleibatterien, aufweisend einen Grundkörper, an dem bei bestimmungsgemäßer Anordnung der Vorrichtung endseitig in die Rohre der Rohrplatte eingreifende Vorsprünge angeordnet sind.
