On the ones I have that are similar lifting on the metal tab at the end with a little force it pulls off. Then the lamp is pulled to the side and taken out. To re assemble put the new lamp in without touching the lamp use a tissue or the packaging material any finger oils on the lamp may cause it to get hot and explode. I usually will clean the protective cover and snap it back in place. Sometimes this cover can be very stiff but they are easier to snap back in place.
