A device for sealing the contact zone between two parts that are movable with respect to each other, of which one forms a shut-off element (1) and the other a sealing seat, contains at least one sealing element formed by a resilient steel strip (2) that extends along the contact zone, is curved to form a hollow section and of which the two longitudinal edges form clamping edges (3) clamped on one of the two parts in contact at a distance from one another equal to at least 10 % of the width of the sealing element. In the closure position of the shut-off element, a sealing zone (4) of the sealing element, which is convex with respect to the sealing seat, is pressed on the sealing seat by a sealing force exercised by the spring. The sealing zone (4) of the resilient steel strip (2) is plastically bent into the shape of a roof with a ridge and two adjacent roof surfaces (5) that enclose an angle from 60~ to 160~. The longitudinal edges of the two roof surfaces (5) away from the roof ridge are plastically bent outward to form another convex bend (6) adjacent to a side surface (7) which is flat at least in a first section and on the free longitudinal edge of which the clamping edge (3) is arranged.
