Abstract
Abstract A conventional type of life preserver has a rectangular shape, with a circular neck receiving opening adjacent the upper end and a slit extending from the bottom of the opening to the lower edge of the preserver. The invention comprises a strap having one end thereof immovably molded into the preserver and extending from one side edge of the preserver to the slit. A pair of oppositely directed D-ring fastening members are mounted on the strap in recesses directed inwardly from opposite sides of the preserver adjacent to the slit. The portion of the strap past the D-rings slidably extends through a sleeve which is molded into the preserver from the slit to the opposite side edge. The strap has an elongated portion which extends around the body of the wearer, with a buckle on its end which may be selectively attached to either of the rings, depending on the direction in which the preserver is facing.
