A harness for securing a nasal cannula to a user for the purpose of delivering oxygen. The harness comprises an upper and lower strap located at the top and rear of a users head, respectively. The upper and lower straps are orthogonally connected at their midpoint by a vertical connecting strap, and contain on either end, an adapted means to secure and support a nasal cannula by looping around the plastic tubing and then attaching onto itself. Two distinct connection points above and below each ear maintain the suspended position of the cannula without deforming its cross section. By providing a three-strap methodology for supporting the nasal cannula and maintaining positive control of the plastic tubing by keeping it suspended above the ears, the present invention avoids commonly associated drawbacks related to existing devices.
