One assembly is adapted to be detachably mounted to a face mask and carries modules for communication accessories. A second subassembly is threadedly attached to the first sub-assembly and carries the valving members necessary to admit air or breathable gases to the face mask and to allow the escape of exhaled gases. The second sub-assembly valve portion is made in two sections which can be disassembled for repair with readily replacable valving elements for easy maintenance.
