1. An apparatus for supplying breathing gases from a gases supply to a user through a breathing circuit to provide an elevated internal pressure in the user's airways, the apparatus comprising:
a first portion configured to contact the user at a first location, the first portion defining an opening configured to allow breathing gases to pass from the breathing circuit to the user; a second portion configured to contact the user at a second location; an adjustment mechanism that moves the second portion in a linear manner relative to the first portion along an adjustment axis such that the apparatus can be adjusted to the user's facial contours, wherein the adjustment mechanism comprises:
an adjuster rotatably clipped to the first portion, the adjuster comprising a first thread element;a second thread element provided on the second portion, wherein the first thread element and the second thread element engage one another such that relative rotation of the first thread element and the second thread element causes the movement of the second portion relative to the first portion along the adjustment axis;wherein, when the adjuster is rotated, the adjuster causes rotation of the first thread element with respect to the second thread element; and an elbow connector configured to connect the apparatus with the breathing circuit.
