摘要

Improvements in compressed air breathing apparatus with frame to carry on the back, especially to be used as a protective device against gases, in which, in the framework to carry on the back have been attached a high-pressure connection block with the piece of gasket for the air inlet as well as holding means for the replaceable clamping of a compressed air bottle provided with a bottle valve and a gasket for the air outlet, characterized in that at the height of the high connection block pressure is provided, in the frame to carry on the back, a retaining fork whose fork opening acts together with one or more guide pins provided on the valve of the bottle so that, once the introduction of these freighters has been made of guide in the opening of the fork, the position of relative coupling between the two pieces is necessarily maintained In addition, in the frame to be carried on the back, a closure cap has been mounted which, in its closed position, on the one hand holds the compressed air bottle and, on the other hand, covers the also the retention fork.
