  • a second section piece (5) consisting of an elastically deformable flexible material, said second section piece abutting an outside of a branch of said first section piece and forming a tubular member, at least one orifice (6) in said second section piece fluidly communicating the inside of said second section piece with the outside of said second section piece, said second section piece being compressible by an opening leaf operatively associated with the opening in the bodywork upon said opening leaf being in a closed position; and

    a third section piece (7, 10, 11) consisting of an elastically deformable flexible material having a hardness of between about 30 to about 35 Shore A being housed within the confines of said second section piece (5), said third section piece (7, 10, 11) forming a sealed tubular member connected to a source supplying a non compressible liquid under a variably controllable pressure to said sealed tubular member of gas-tight and liquid-tight construction and which is expansively deformable in response to said pressure generated by said liquid for coming into surface contact with an interior wall surface of said second section piece (5) so as to enhance the sealing and soundproofing properties of the seal.
