1. A mask structured to be coupled to a head of a patient with a headgear for use in communicating a flow of breathing gas to an airway of a patient, the mask comprising:
(a) a patient interface including:
a faceplate, and
a cushion having a first end coupled to the faceplate and an opposite second end that is structured to sealingly engage a portion of a face of the patient about one or more airways of the patient; and
(b) a frame including:
a first arm member having a first end coupled to the patient interface via a first coupling arrangement and an opposite second end structured to be coupled to the headgear, and
a second arm member having a first end selectively coupled to the patient interface via a second coupling arrangement and an opposite second end structured to be coupled to the headgear, wherein the second coupling arrangement requires a lesser lesser uncoupling force to uncouple than the first coupling arrangement
wherein the second coupling arrangement comprises:
a ridge extending from the first end of the second arm member; and
a groove defined in the faceplate that is structured to receive the ridge therein,
wherein the groove includes a plurality of segments comprising: a first segment, a second segment extending generally parallel to the first segment, and a third segment extending between, and generally perpendicular to, the first segment and the second segment,
wherein the ridge includes a plurality of segments comprising: a first segment, a second segment extending generally parallel to the first segment of the ridge, and a third segment extending between, and generally perpendicular to, the first segment of the ridge and the second segment of the ridge, and
wherein the first, second, and third segments of the ridge are sized and positioned to correspondingly engage the first, second and third segments of the groove.
