(54) | Improved seal |
(57) This seal includes a flat plate (1) from which a tailpiece (2) extends, which is
provided with a peripheral dentate (5) in its intermediate area; this plate (1) is
linked to a tubular passage (3) with a frusto-conical mouthpiece (3a), a cylindrical
intermediate portion (3b) and elastic tabs (3c) forming means for retaining the dentated
portion (5) of the tailpiece. The dentated tailpiece (2) has a ring-like reinforcement
(4) in the connecting area with the plate (1), and a thickening (6) at the front end
of the dentated piece (5) which only enables its introduction in the tubular passage
(3) through the end corresponding to mouthpiece (3a). |
