A respiratory system composes an oxygen supply, a vented respiratory mask, a hose coupled to the oxygen supply, and a connector apparatus joining the respiratory mask and the hose. The connector apparatus may comprise mask connector member to govern fluid flow through a vent in a mask, a mask valve received in a mask fluid flow passage movable between a rest position in which the mask fluid flow passage is blocked and an actuated position in which the mask fluid flow passage is unblocked, a biasing member biasing the mask valve towards the rest position, and a hose connector member to be secured to a fluid hose. The hose connector member includes a valve actuator to move the mask valve to the actuated position when the hose connector member is coupled to the mask connector member.
