Abstract
The invention relates to breathing apparatus, particularly of the open-circuit type, comprising a backpiece equipped with means, particularly involving straps, to allow it to be worn on the back of a wearer, the backpiece being intended to support at least one cylinder equipped with a valve, the backpiece being equipped with a coupling which, intended to collaborate with the valve, is connected to a regulator. The coupling comprises an air intake tube on which a bushing is mounted such that it can pivot and move in terms of axial translation. The bushing is mounted in a sleeve that forms an operating knob, is prevented from turning in the sleeve and is free in terms of translational movement with respect to the latter.
