Abstract
A user interface (22) with headgear (29) is disclosed where a flexible conduit (24) supplies gases to the patient interface and the conduit is connected to the headgear by a sliding connection or support portion (26). In one form headgear may include a transverse strap which the conduit is attached to. In other forms various sliding straps constrain the conduit such that forces on the conduit are transferred to the headgear not the interface. Interface vertical height and angular adjustment mechanisms are also disclosed.
