Abstract
The device is for connecting the shell or face piece of an oral nasal breathing mask of a fighter pilot to a helmet. It comprises two fasteners each placed on one side of a median vertical plane of the helmet and one at least of which is provided with a quick fastening and unfastening attachment device. Each fastener is formed as a link rigid in the vertical direction and non-extensible, arranged to allow rotational movement of the mask with respect to the helmet about a direction perpendicular to the direction of the link and substantially parallel to said median vertical plane.
