Abstract
Abstract A water outlet has a collector funnel for water to be drained from a roof surface or the like. A ring is fitted, with a groove and projection bayonet-type fixing, in the funnel, and thereby secures to the funnel a covering sheet or film. The sheet is intended to extend over an annular flange on the funnel, and be joined to the roof surface, to seal the outlet to the roof surface. The ring is preferably embedded in the sheet.
