1. A headgear clip for a positioning and stabilising structure of a patient interface, comprising:
a mechanical structure configured to mechanically engage the headgear clip to a headgear connection point of a frame assembly,
wherein the mechanical structure is configured to allow the headgear clip to rotate relative to the headgear connection point when the mechanical structure is magnetically engaged with the headgear connection point and headgear tension is applied;
a magnet configured to magnetically engage the headgear clip with the headgear connection point; and
a slot configured to receive a headgear strap passing therethrough,
wherein the mechanical structure is configured to prevent linear displacement of the headgear clip in a direction substantially parallel to the Frankfort horizontal direction when headgear tension is applied,
wherein the mechanical structure includes a raised wall that forms a space configured to receive the headgear connection point,
wherein the mechanical structure includes outer engagement surfaces configured to engage the headgear connection point, wherein the outer engagement surfaces are substantially smooth so as to minimize relative friction and physical obstruction thereby permitting 360° rotation of the headgear clip relative to the headgear connection point,
wherein at least a portion of the outer engagement surfaces of the raised wall is sloped and configured to engage an undercut provided to the headgear connection point to facilitate retention of the headgear clip on the headgear connection point,
wherein the space formed by the raised wall is configured to receive a raised surface provided by the headgear connection point, wherein the raised surface is sloped to provide said undercut, and
wherein the sloped portion of the raised wall is configured to abut the sloped, raised surface of the undercut when headgear tension is applied to facilitate retention of the headgear clip on the headgear connection point.
