The sill includes at least one flat and elongate gasket element, of the tongue type, fixed via one of its longitudinal sides to the lower edge face and a sealing and travel groove made in the floor surface across the opening concerned and intended to house the gasket element able to collaborate in travel with one of the longitudinal edges of the groove.
