Hi Philipp,

I don’t know what happened: I believe I started a new thread with a new subject. My mail program makes sometimes strange things…

Anayway. Thanks for your response. In the meantime I found another solution:

\starttext

\define[2]\MyChapter {#1.\,Kapitel: #2}
\setuphead [chapter] [command=\MyChapter, page=no]

\setuphead [chapter] [numbercommand=\groupedcommand{}{ Kapitel:},page=no,sectionstopper=.]

or

\setuplabeltext[en][chapter={, Kapitel:}]
\setuphead [chapter] [page=no,sectionstopper=.]
