@urbanus+Magnusian:
Thanks. I will check that. But shipping things from outside germany isnt realy comfortable for me. But it is a option.
@rootwyrm
Yes, why arent broken. But they havenīt realy contact with the cable.
Sorry but i donīt understand what you mean with:
"They are staggered-offset by design as part of the retention and keying mechanism.
I would however, consider reworking the drain strap (the metal piece) since it looks like it may be pulling out on the inner."
My school english is not good enought for that 
What he means is that the connectors look like that on purpose, they aren't broken.
The other part means that the metal connector for the wire that goes to the steel plate looks like it needs to be resoldered.
You will have to do a bolt mod because replacing the hammer & spring will require the keyboard to be disassembled.
No offence but that's bad advice. Bolt mod is complete overkill for a trivial problem like a bent spring.
As per my previous advice, google sandy55's chopstick of death. It's a simple method to pull and replace a spring with no disassembly required.
None taken, didn't know about the chopstick method, though I am still wary of it.
OP, if you don't want to order the part from Unicomp to get the spring, you'll have to harvest one from another M. It's not a generic spring. I doubt the postage for both such a small and low-weight item would be all that high even internationally, and I'd be surprised if customs gave you crap over it.
