Ventilating pipe (1) comprises a pipe section (4) passing through a roof covering plate (2) on which a cap (24) overlaps a tapered ring section (25) of an apron (S). The cap clips onto the apron using snap-in locking protrusions (32) engaging in notches in the apron. The inward-facing snap-in locking protrusions are slidably arranged on the ring section and can be inserted into openings (33) to engage with an edge. Preferred Features: The apron is molded on the pipe section in one piece. |
