ABSTRACT:
A roof vent pipe (1) having a mouth-side grid structure (G) is formed at least in part of annularly extending spokes and a cover cap (2) located above the spokes. The cap is interengaged via downward directed projections with the upper pipe end. To obtain an optimal attachment of the cover cap, a central projection (4) of the cover cap (2) engages in form-locked manner into the inside of an annular spoke (6). Support fingers (10) rest on at least one further outward lying annular spoke (11) are arranged concentrically thereto, and protrude from the lower side of the cover cap.
