Bei einer Schutzeinrichtung für Atemschutzgeräte, und zwar insbesondere für Unterwasser-Atemschutzgeräte mit wasserempfindlichem Atemkanister, ist der Atemkanister (7) mit einem Atemschlauch (6) mit Mundstück (1) verbunden. Um ein Eindringen von Wasser in den Atemkanister beim Anlegen des Gerätes unter Wasser zu verhindern, ist eine Schutzvorrichtung vorgesehen, die aus einem Verschlußventil (3) und aus einem Wasserauffangelement (10) besteht. Diese Schutzvorrichtung ist im Strömungsweg des Atemschlauches (6) zwischen dem Mundstück (1) und dem Atemkanister angeordnet. Das Wasserauffangelment ist mit einem Speichermaterial (16) gefüllt, das Wasser durch Kapillarkräfte festhält. Das Speichermaterial (16) ist gekörnt und besteht z.B. aus Kieselgel oder Tonerdegel.
