Abstract: A reinforced flexible seal (101 and 201) for sealing a gap or space, such as a gap or space between an edge of a wall, fence, door, door leaf or wing, port or window and a surface adjacent to the wall, fence, door, door leaf or wing, port or window is provided. The flexible seal may be used to provide a barrier below a door leaf or door wing in order to avoid entrance of for example unwanted animals. The reinforced flexible seal has a width and a length and comprises a flexible outer material (102a, 102b, 202a, 202b), and a plurality of elongated metal wires (103, 203) embedded in the flexible outer material and running substantially in a longitudinal direction of the reinforced flexible seal with at least part of said elongated metal wires arranged at a distance to each other. For at least one of the embedded elongated metal wires, at least part of said metal wire holds several bent, bulging or wavelike deformations in the longitudinal direction of the wire.
