1. A sealed and thermally insulating wall for a tank for storing fluid, comprising:
a heat-insulating panel (1) having an inner face and a periphery; and a sealing plate (7) having an inner face designed to be in contact with the fluid contained in the tank and an outer face anchored to the inner face of the panel (1) in the region of a plurality of anchoring areas (14), said sealing plate (7) comprising at least one corrugation (8; 9) which protrudes from the side of the inner face of the sealing plate (7), extending in a direction d1 (x; y); in which: the inner face of the heat-insulating panel (1) comprises a stress-relieving slot (15; 16) between two adjacent anchoring areas (14) arranged on either side of said corrugation (8; 9), said stress-relieving slot having an axis extending in the direction d1 (x, y) so as to permit a deformation of the corrugation transversely to the direction d1 (x, y); and the stress-relieving slot (15; 16) has a length which is less than the dimension of the heat-insulating panel (1) along the axis of the stress-relieving slot (15; 16) and does not extend as far as the periphery of the heat-insulating panel (1).
