The invention related to the condensate drain on an adjustable-angle roof ventilator of the cover/coupling type. The duct passing through the roof from below terminates in the lower section of the space enclosed by the coupling. A connector surface extends from the lower piece of the inside of the coupling innards to the outer surface of said duct. At the lowest lying contact patch of said connector surface with the coupling surface, the coupling surface is pierced by an outlet opening.
