Abstract: A vehicle headlamp in which an optical unit for a sealed beam is mounted between a carrier ring fixed to the vehicle and a removable cap ring. On the carrier ring two diametrically opposed pins are supported in bearing bushes to be coaxially rotatable and axially displaceable. Both pins are fixed to a resilient clip that bears on cam faces on the outer ends of the bushes. Upon pivoting the clip, the pins are jointly rotated and, by the action of the cam faces are axially oppositely displaced. As they are extended outwards they engage recesses in the cap ring to secure it to the carrier ring. Eccentric portions on the outer ends of the pins thereupon bear on the recesses with further rotation of the pins to draw the cap ring and carrier ring together to grip firmly an interposed rim of the optical unit.
