Abstract
A lightweight, easily maintainable passenger oxygen mask is provided with a face mask sized to cover the mouth and nose of a passenger and a reservoir bag in communication with the face mask. Oxygen is permitted to flow through the bag into the mask, while being prevented from flowing back into the bag. A bag connector is positionable within the bag for holding the bag against the face mask, and cooperative structure is provided on the connector and the mask for providing snap-fit connection between the connector and the face mask to permit the bag connector to be selectively, manually attached to and removed from the face mask.
