a second inlet conduit structured to connect with the nasal assembly at the second lateral side of the nasal assembly and deliver pressurized air to the breathing chamber through the second air-delivery passage of the nasal assembly;
a head-mountable flow generator connector to connect the first inlet conduit and the second inlet conduit with a supply of pressurized air, the head-mountable flow generator connector being shaped to position on a top of a head of the patient when the nasal assembly seals around the nasal passages of the patient and being shaped to direct the supply of pressurized air to the first inlet conduit and the second inlet conduit; and
a rear strap to extend between the first inlet conduit and the second inlet conduit and around a rear portion of the head of the patient when the head-mountable flow generator connector is positioned on the top of the head of the patient, the rear strap being mountable to the first inlet conduit and the second inlet conduit on respective sides of the head of the patient so as to retain the first inlet conduit and the second inlet conduit in an operative position extending from the nasal assembly upwardly along the sides of the head and toward the head-mountable flow generator connector at the top of the head of the patient.

Abstract
A nasal assembly for delivering breathable gas to a patient includes a frame having an integrally formed first connector portion. A nozzle assembly includes a gusset or base portion and a pair of nozzles. At least one inlet conduit is structured to deliver breathable gas into the frame and nozzle assembly for breathing by the patient. A pair of second connector portions are removably and rotatably connected to respective first connector portions of the frame and are in communication with respective inlet conduits, e.g., directly or via angle connectors. A headgear assembly is removably connected to the pair of second connector portions and/or the angle connectors so as to maintain the frame and the nozzle assembly in a desired adjusted position on the patient'"'"'s face.
