This device comprises a mask 2 fitted with an intake connector 12, with a discharge valve 20 and with a regulator 4 fitted with an upstream connector 46 intended to be connected to a supply of breathing gas and with a downstream connector 50 connected to the mask 2 by means of a flexible hose 6. It is characterised in that the mask 2 is fed with breathing gas, by means of control buttons 68-86 located on the regulator 4, through a non-return valve 24-30, separated from the used gas discharge valve 20 and lying in a plane above the said discharge valve. The invention can be used in lighter-than-air aircraft such as gliders, free balloons and non-pressurised aircraft. <IMAGE>
