The seal has a deformable sleeve (2) made of a resilient material for receiving a beam of yarn or cable. The sleeve comprises a projection (5) i.e. annular lip, of a sleeve tube on an outer surface in a non-mounted state. The projection is intended to bear against a face of a through-wall (30) and a window (13) on an inner surface. Another projection (16) is invaginated to an end of the sleeve, protruded outside the sleeve in a mounted state and defined with the former projection. The latter projection makes a space to be intended to elastically clamp the through-wall. |
