A light effect system includes a light source and one or more aperture elements interposed between the light source and an exit lens of the system. The aperture element comprises at least one aperture and at least one light effect element positioned therein. This invention concerns a system where the aperture element comprises at least two “fingers” partly surrounding each light effect element in at least 180° of the circumference. These snapping “fingers” engage with the contour of the outer surface of the said light effect element in order to hold the light effect element in position in the aperture, and the said fingers are formed of a flexible material. Hereby, it is achieved that the locking and releasing of the light effect component can be done by push and pull in an ideal perpendicular direction to the light path. In other words, no angling, bending or twisting is necessary, so a minimum of space is required.
