Abstract: An emergency exit for a helicopter is described that comprises: a wall defining an opening; a removable part engaging the opening in a removable manner; and a seal interposed between the wall and the removable part. The seal is transformable between: a first configuration, in which it prevents removal of the removable part from the wall following application of a predetermined load on the removable part; and a second configuration, in which it allows removal of the removable part from the wall following application of the predetermined load on the removable part. The emergency exit comprises an insert interposed between the seal and the wall; at least one of the insert and the seal comprise at least one tooth engaging a recess with a shape corresponding to the tooth and defined by the other of the insert and said seal, when the seal keeps, in use, the removable part constrained to wall.
