A mask ( 10 ) for supplying gas under pressure to the nasal airway of a human includes a manifold ( 30 ) including means ( 36 ) for connection to a gas supply means, a gas supply element or elements ( 26 ) for providing said gas to the nasal airway without pressurising the exterior of the nose and a flexible strap ( 12 ) formed from an elastomeric material for securing the manifold ( 30 ) in position. The strap ( 12 ) extends either side of the manifold ( 30 ) and is shaped to generally conform with the shape of the upper lip and adjacent cheek area to act as a distributed anchor means for the mask ( 10 ).
