ABSTRACT:
A breathing apparatus comprises a cylinder assembly supported by a harness through a mounting bracket. The bracket has a leg with an open-ended slot into which a grooved portion of the cylinder assembly is passed. The assembly is secured by screwing a pressure-reducing valve onto the shut-off valve of the cylinder assembly, in so doing a knurled ring on the pressure-reducing valve coming into position adjacent to an edge of the bracket to prevent subsequent withdrawal of the cylinder assembly from the slot.
