An extender for motor vehicle sun visors includes two opposed plastic panels hinged together by a hinge section which is integral with the plastic panels. A plurality of U-shaped spring elements extend around the outer surfaces of the hinge section and the plastic panels, engaging the outer surfaces of the plastic panels, forcing them together with a relatively constant force to ensure secure gripping of a conventional sun visor by the extender, regardless of the effects of temperature on the elasticity of the hinge section.
