Abstract
A mask tightening strap, whereby a tightening device of a conventional diving face mask or swimming goggles is configured to comprise a protective sleeve attached to an inner side of a tightening strap. A fastening strap is configured on one end of the protective sleeve close to a frame of the diving mask. A hollow out portion is defined by a side of the fastening strap, and thereby enables a retaining ring of a breathing tube to clasp onto a strap in the hollow out portion. The protective sleeve can thus realize complete separation of the retaining ring from skin of a diver, and thus not only makes wearing of the face mask more comfortable, but also averting hypersusceptibility skin reactions from occurring or scratching of the skin of the diver.
