A device for securing a nasal cannula to a patient's head is disclosed. The device utilizes a thin round elastic band placed behind the patient's head and is attached to the cannula gas supply tube (20) by cord couplers (30, 35). The cord couplers (30, 35) are slidably attached to the gas supply tubes (20) to allow fast and easy adjustment to size. The device is light, comfortable, inexpensive and simple to use. It prevents painful hair entanglement and allows single handed deployment and adjustment of a nasal cannula, while affording secured placement of the cannula during patient movement or sleep. Additionally, a nosepiece (10) having a downwardly oriented U shape or arcuate fold in its center portion is disclose to prevent the cannula nosepiece (10) from exerting excessive pressure against the patient's septum. A method of use is also disclosed.
