A flexible seal intended to be fixed between a fixed part and a mobile part of an aircraft, the seal comprising an elongate hollow body, a shoe secured to the hollow body, intended to be fixed to the fixed part, a blade secured to the hollow body and designed to extend from the hollow body towards the mobile part, the blade having a leak edge having a non-linear edge, such as with notches or chevrons. The provision of a notched leak edge reduces a pressure differential on either side of the blade, and by allowing the air to pass between the blade and the fixed part just before the contact with the fixed part, the lifting of the blade is prevented.
