The invention relates to an anti-explosion screen comprising at least one panel (2, 3, 4) consisting of a blast shielding material, and a set of holding connectors (11) that are connected to the panel, on one side, by means of fixing points (12, 13), are can be fixed, on the opposite side, to at least one anchoring point (14, 15) located at a distance on one side of the screen. According to the invention, the lengths of the holding connectors (11) are adapted according to the positions of the anchoring points and corresponding fixing points, in order to maintain the screen in an upright position when it is subjected to an essentially horizontal force which distances it from the anchoring points and stretches the connectors.
