ABSTRACT:
A retainer for securing a nose pad on an eyeglasses frame, the retainer being composed of a flat, one-piece pad arm having a receiving opening in the form of an elongated hole, and a retaining element of plastic secured to the nose pad, the retaining element having a constriction and being receivable in the receiving opening of the pad arm to be locked in the receiving opening by engagement of the constriction in the opening. The pad arm is a bilaterally symmetrical structure having a first end in which the opening is formed, is made of material which extends continuously around the opening and is substantially inelastic around the opening. The opening cross section of the elongated hole is selected and the retaining element is formed such that when the constriction engages in the receiving opening, a transition surface of the retaining element is engageable with the pad arm for allowing the retaining element and the nose pad to be pivotable and tiltable relative to the pad arm.
