A visor includes a visor body receiving a longitudinally extending pivot rod to which there is fixedly mounted a generally U-shaped resilient clamp surrounding the pivot rod. A cam is coupled to the clamp and includes an actuating lever for selectively operating the clamp for releasing the pivot rod from the clamp allowing the visor body to slide longitudinally with respect to the pivot rod. In a preferred embodiment of the invention, the clamp is made of a resilient polymeric material having a cylindrical aperture adjacent its closed end for lockably receiving the pivot rod therein. Extending between the legs of the generally U-shaped clamp is an L-shaped cam rod having a flat extending between the legs such that they remain in a fully closed, clamped position while locking the visor body with respect to the pivot rod. The cam rod can be rotated by the actuation of a lever coupled thereto for spreading the legs of the U-shaped clamp apart for releasing the visor rod.
