Abstract: A mounting kit and a method for connecting a sprinkler head to a coupling piece with threading, which is cast into a concrete ceiling. To enable installation of a sprinkler head concealed or visible in concrete ceilings, without costly steps for forming recesses in the concrete ceiling, it is proposed that the mounting kit include a hollow cylindrical cap with an end surface that is closed toward the outside of the concrete ceiling, a sleeve that encompasses the perimeter of the cap and a threaded element, which can be screwed into the threading and which separably connects the sleeve to the coupling piece. When the concrete ceiling is being cast, the cap is fastened to or on the concrete formwork on the outside of the concrete ceiling.
