This pic will speak for me...

Seems that I did somthing wrong :)

If anyone could tell me how to place attachments correctly...

That's not attachments, that's a bad skeleton. If you move the bones around in Milkshape, or the skeleton in your reference file and your animations are too different, then you get that train wreck looking thing.

The always brutally honest Cheeto. ;)

I think it's because you attached the w_ model instead of the p_ model.

No, Cheeto's nailed it. Mayhaps you've accidently hit the select all button, and then used either move or scale tools. Both will shift skeltons, and it will be ****ed up completly.

It was effectively a problem with the skeleton, I 've used another one and the problem disapears.

I see you have learned as I have that ctrl+A is a bad bad bad bad bad bad button combination in Milkshape lol. I used to always use it and then move what I thought was a vertex only to have moved the skeleton too. I wish I had saved this one model I had from 3.1 where the head was the hands and the body rotated around when you ran. It was like night of the living dead lol. Hope this helped you.
