The front section of the stepped through-hole is formed as a sloped counterbore. The stepped cylindrical body has a rear section formed as a small-diameter, sloped cylindrical body which is shaped and sized according to the sloped counterbore, so that the small-diameter, sloped cylindrical body of one filter unit is insertable into the sloped counterbore of another filter unit.
