The subject of the invention is a roller blind which is assembled in a chain-like manner from identical profile bars which can catch one into the other. In said blind, next to each hook pair (hooks 6, 10), there is arranged a wedge surface (F) which is inclined with respect to the direction of displacement, belongs to one profile bar and is intended for a nose (8) of the second, neighbouring profile bar. The main purpose of this is to prevent criminals from being able to push the roller blind up to open it. <IMAGE>
