Device comprising a demand valve () for delivering breathable gas to a diver and a fluidic connector () that can be selectively connected to the demand valve (), the demand valve () comprising a breathable gas supply inlet (), characterized in that the demand valve () and/or the fluidic connector () comprise a blocking device () for selectively blocking the connector () on the demand valve () when the connector () is fastened to the demand valve () via the catching members (), the blocking device () being selectively moveable and/or deformable between a first configuration of blocking relative movement between the demand valve () and the connector (), and a second configuration of unblocking, allowing relative movement between the demand valve () and the connector ().

Demand valve device for use by diverse and selectively connectable fluidic connector

Device for supplying breathing gas, particularly for a mouthpiece of a diver, including a casing incorporating, between an inlet orifice for the supply gas and an orifice or the outlet of the gas for the purpose of breathing: a pressure-reducing valve system having a member for controlling the force necessary to open the valve, a member for controlling the flow rate of the gas let into the outlet orifice, the supply device also including a manually actuatable control element capable of interacting with the control member in order to adjust the force necessary to open the valve, characterized in that the control element is capable of interacting also with the member for controlling the flow rate of gas in order to ensure both the adjustment of the force for opening the valve and the adjustment of the flow rate of outlet gas.
