The diving breathing apparatus comprises a monobloc unit of two BP regulators (1,2). Two flexible tubes (1c, 2c) supply breathing gas to the BP regulators from a pressurized bottle connected by two quick turning connectors (1b,2b). A valve (4) operated by the diver is rotated into a position allowing the diver to breathe through the connector in the regulator (1) whilst isolating the second regulator (2) or conversely.
