The spring itseelf is missing in the diagram I would say. I solved it
by
bending the spring (the long iron "wire") outwards a bit. It was not
possible to completely get it right using the adjusting screw. I had
to
bend the spring slightly.

Thank you all very much for the help: you gave me lots of useful
tips.
I find it far more difficult to adjust then a normal Shimano caliper
brake
for racing bikes.


I agree. This is why I recently got rid of my Cannondale touring bike
(and other reasons) and opted for a long-reach caliper design (Gunnar
Sport), so as to be able to use fenders. I admit there are some
applications for which there is no alternative to cantilevers but, like
you said, they are way more complicated.
