A snap hinge closure connects two parts, such as, for example, a lower and an upper part of a closure. Both parts have casing walls which, in the closed position of the hinge, match vertically above one another. On both sides of the film hinge, tension bands are positioned, which, in the closed position, are tensed. The tension bands are held, with their ends, in recesses (11) in the casing walls, and have, over their entire length, an approximately uniform cross section. The outermost surfaces of the tension bands align with the casing external surfaces.
