Abstract
An electromagnetic seal consists essentially of an oblong metal plate with two bends along two parallel longitudinal bending axes (D1, D2) defining on the plate two lateral flanges (34, 35) inclined relative to a central panel (36), and an central oblong opening (29) which has a width (a) slightly less than the distance (b) between the bending axes so that parts of the central panel situated on the longitudinal edges of the central oblong opening, separated before bending by cut-outs on the transverse edges of the opening and between the bending axes and the central oblong opening, are adapted to form oblique extensions of said lateral flanges in the region of the central oblong opening.
