The sealing device comprises a plate (1), seals (7, 8, 9, 10) located at the edges (3, 4, 5, 6) of the device and fastening means, where the plate is large enough to cover the letter box slot such that the seals make contact with the door. The fastening means, which may comprise magnets (11,12) or double sided adhesive tape, is used to attach the sealing device to an existing letter flap (2), preferably located on the inside of the door. In an alternative embodiment at least one of the seals may be directly to the door rather than the sealing device. |
