A connection portion (100) of a respiratory mask (12) for receiving an air delivery tube is disclosed. The connection portion comprises a relatively thin-walled flexible portion (96) configured to sealingly receive the air delivery tube in aperture (90). A relatively rigid portion (98) surrounds the relatively thin-walled portion (96). The relatively thin walled portion (96) is configured to flex, move or bend towards the front of the mask so that when the air delivery tube is inserted into the aperture (90) a seal is formed and the mask (12) is substantially decoupled from movement of the tube. |
