ABSTRACT OF DISCLOSURE The invention relates to a stopper with valve for a storage battery which permits the gases evolved by the storage battery to escape only above a precise specific pressure higher than the atmospheric pressure. The valve includes a diaphragm clack maintained gripped in a fluid-tight manner, at its periphery, between the body of the stopper and a hood which covers a calibrated spring normally keeping the valve closed. The hood is secured on the body solely by ratchet engagement of these two members which have corresponding frustoconical surfaces and of which at least one is deformable. The stopper with valve is for application to fixed or starting storage batteries in order to lessen the consumption of water in the batteries.
