Claim 20:
21. The air delivery conduit according to claim 1, wherein:
the end portion of the first cuff has a retention bead that extends radially inward therefrom and is configured to engage an exterior surface of a tubular connector of a patient interface,
the first cuff comprises a first stop surface positioned between the fixture and the retention bead in an axial direction relative to the first cuff, the first stop surface extending radially inward to form a first hole having a smaller diameter than the retention bead such that the first stop surface is configured to contact an end of the tubular connector of the patient interface,
the plurality of wires include a heated wire configured to generate heat,
the fixture of the first cuff is molded around the thermistor,
the fixture is longer in a direction parallel to a flow direction of pressurized breathable air through the first cuff than in a direction perpendicular to the flow direction of pressurized breathable air through the first cuff,
one of the plurality of wires is configured to transmit a signal based on a temperature sensed by the thermistor to a controller of the PAP system,
the second cuff comprises a sealing lip structured to engage and resiliently deform against an exterior surface of a tubular connector of the PAP system,
the second cuff includes a second stop surface positioned inward of the sealing lip in an axial direction relative to the second cuff, the second stop surface extending radially inward to form a second hole such that the second stop surface is configured to to contact the tubular connector of the PAP system, and
the end portion of the first cuff includes an entry surface that is curved or chamfered from an axially outward edge of the end portion such that a diameter of the end portion decreases in an axial direction into the first cuff from the axially outward edge of the end portion.
