Abstract: A system for mounting a rollable screen, includes: a screen roll defining an end having a hollow tube; a coupling piece including: a neck element, having a sleeve adapted to be positioned in axial direction inside the tube. The contact surfaces included in the sleeve contact the tube, and recess surfaces in the sleeve define axial channels between the neck element and the tube; a transitional element fixedly connected to the neck element, one or multiple anchoring elements, adapted to fasten the neck element detachably to the tube. In an anchored state the anchoring elements are clamped inside the axial channels, with an even clamping along the axial direction.

Abstract: The invention relates to the field of side guides for screen devices for reliable screens. The invention furthermore concerns methods for mounting and removing the side guide.
