ABSTRACT:
A device which, under the effect of water, separates the cartridge-like receiving means and the connector of a retainer for an oxygen mask, preferably for pilots. The receiving means is connected with a support, for example a helmut on the head of a person, and the connector, to which the oxygen mask is attached, is safely held in the receiving means with securing elements which are under tension and which can be released by a bracket mounted on the connector. The device includes a housing which is held directly on the connector. A spring bolt, which can be moved against the force of a compression spring, is guided in the housing. A lever arm which can shift the bracket is mounted on the spring bolt. A self-acting element, which loses its rigidity in water, and which holds the compression spring in the tensioned position, acts on the spring bolt.
