The screen (5) has a beaded casing to hold it by friction and/or positively to the cylindrical wall of the fiber sealing rin (4) once plugged into place. The screen can be integral to the casing, the casing being conical and elastically flexing towards the of the screen. The downstream endface (12) of the connection pipe (1) flange (13) has a narrowed part (14) to form an additional positive axial securement for the screen (5). An annular part of the screen normal to flow adjoins a hat-shaped center zone and otherwise beaded onto the screen casing part and the axial length of this casing equals the thickness of the sealing ring (4).
