Abstract
An adjustable retaining strap for eyeglasses includes an elongated tubular member formed of a flexible resilient material. End portions of the tubular member are reverse-fold to define end loops that are retained by end sleeves each having a passageway therethrough. An end plug member is matably received in the end portion of the tubular member and is sized to prevent withdrawal of each tube member from its respective retaining sleeve. A central portion of the tubular member between the end loops may be configured in a central loop received by a central sleeve. A central bead may be received on the bight of the central loop to prevent its withdrawal from the central sleeve.
