Abstract
A quick adjust strap for ready connection and release of a diver's face mask. A headband is connected to brackets on the sides of the face mask. One end of the headband is received in a ring of one bracket and nipples thereon lock with a slider member thereof. A ribbon of material is connected to the other end of the headband and is received through a ring of the other bracket and folded back over itself. The ribbon is coated with a tacky material, such as a Velcro cloth and a Velcro gripper, which when brought into contact will maintain the fold and secure the headband about the diver's head with precise adjustment. Sandwiched between the gripper part and the cripping cloth is a finger tab that may be readily gripped by the diver to affect a quick release of the face mask from the diver's head. The finger tab is larger than the bracket by which it is attached to the mask so that accidental release and loss of the mask is prevented.
