ABSTRACT OF THE DISCLOSURE A strap and retainer for a diver's mask, or other mask to be held on a user's face. The retainer is comprised in part of a molded portion of the frame of the mask with a movable clip portion therein which is pivotally mounted. The movable clip portion is mounted into a molded pocket in the frame of the mask that receives the clip. The clip comprises a main lever portion that is pivotally mounted in the pocket with an angular spring arm portion that rides within the base of the pocket. At the other end of the pivotal lever portion from the spring portion is an angular barb or tooth having a substantially upright angular face portion and a sloping angular face portion. The strap comprises a plurality of ribs, one side of which is substantially normal or at a right angle to the longitudinal relationship of the strap, while the other side of the rib has a sloping angular portion. The sloping angular portion can slide under the tooth of said lever against the sloping angular face portion thereof, while said normal angular face portion is engaged against the upright angular face portion of said lever tooth to block the movement thereof when it is under tension and impressed thereagainst. The strap is connected to the mask frame by a cylindrical transverse roller mounted into the pocket around which the strap is looped in a relatively friction-free manner. -2-
