<p>A covering and protective device for machines and systems, in which a plurality of covering elements (2a - 2e; 21a - 21d; 36a - 36d, 45a - 45c) are slidably connected to one another, one after another, to form at least one covering and protective mantle (3; 31; 43) which can be extended and shortened in a predetermined direction (D; D1, D2) in which each covering element (2a - 2e; 21a - 21d; 36a - 36d, 45a - 45c), with reference to the direction of extension (V2) of the mantle (3; 31; 43), has a front profile (9; 28; 41) and a rear profile (10; 29; 42); in each set of three consecutive covering elements (2a - 2e; 21a - 21d; 36a - 36d, 45a - 45c), the front profile (9; 28; 41) of the rear covering element and the rear profile (10; 29; 42) of the front covering element are connected to one another by belts (11, 12; 32; 44) which are wrapped around the intermediate covering element at or close to at least one of the profiles (9, 10; 28; 41) of the latter.
