The present invention relates to a patient interface (3000) for providing a flow of air at a therapeutic pressure above ambient air pressure to a patient throughout the patient's respiratory cycle, the patient interface comprising a frame (3310) comprising a multi-hole vent (3400) configured to washout exhaled air including exhaled carbon dioxide, the frame comprising a frame connection region (3312), a short tube (4180) having a first end that is permanently connected to the patient interface and a second end having a swivel cuff (4190), the swivel cuff being configured to be connected to an end of an additional gas delivery tube (4178) to receive the flow of air during use, a retaining structure (3242) removably attachable to the frame and having a shape and/or configuration that is complementary to a shape and/or configuration of the frame connection region, a seal-forming structure (3100) arranged to surround an entrance to the airways of the patient so as to facilitate the supply of air at positive pressure to the airways, the seal-forming structure being configured to leave the patient's mouth uncovered in use, and the seal-forming structure being constructed from a silicone material, and a positioning and stabilizing structure (3300), comprising at least one rigidiser arm (3302) and a mechanical clip assembly releasably detachably connecting the rigidiser arm and the frame, and a stretchable strap (3301) comprising a textile material and removably engaged with the rigidiser arm.
