A life preserver comprising a buoyant toroidal body having spaced yieldable strap members surrounding at least a portion of the toroidal body, a length of rope extending around the inner periphery of the toroidal body and passing through the central portions of the strap members whereby the rope is maintained in a normal stowage position substantially adjacent the inner periphery of the toroidal body, the rope having the opposite ends thereof extending radially outwardly beyond the outer periphery of the toroidal body and through a passageway for connection with a retrieving cable whereby the rope may be moved radially inwardly against the force of the yieldable strap members to snugly engage the body of a victim disposed within the interior or central opening of the toroidal body to facilitate rescue of the victim without assist from the victim himself. |
