A collar tie does not bear the weight of the roof. It holds the truss and walls together to prevent them from spreading out

Google roof truss and read about its function and parts. Or tear it off and keep your fingers crossed.
It is not a collar tie.
 
The rule in this case doesn't go from wall to wall, it's cut in the middle.

If it is as you describe, then TS can remove the beam.

TS can see this best for themselves.

You mean that if the tie beam doesn't go wall to wall, it has no effect on the moment or tensile force in the wall? That's wrong, but the fastening will indeed take on significant load.

Exactly, and this is not a "tie beam" as we concluded earlier in the thread.

I greatly appreciate everyone involved in the thread. I'm seriously considering removing the loosely hanging board and moving it up a bit, fastening it in a better way—both in the old outer wall and in the load-bearing roof beam. This way, I should get more ceiling height and a more stable structure.

Now I did have 60 cm of snow on the roof at the beginning of the year without seeing any problems with the existing construction...
 
Put a proper hanband in place BEFORE you dismantle the existing studs, so you can be completely sure that nothing happens.
 
I take one at a time, so it should be okay. As mentioned, it's attached with ONE nail at one end and TWO nails at the other end. With an air gap between the studs. I am sure that this joint doesn't bear any load at all - otherwise, the nail would have bent.

Why are you asking here if you're sure?

@elpaco and @hantverkare1

I hinted at it in the first post. You don't need to feel hurt in any way. I appreciate the posts.

Moreover - "before I was sure I was dead sure" - i.e., I can be wrong, likely!

If I'm not too unlucky in my thinking, the horizontal rule takes no load at all and should be removable?

It takes no vertical load. It can take torsional load. It can take horizontal load. If the attachment is very weak, the load it takes will be weak.

I believe neither I nor the craftsman are hurt. I think we're trying to get you to understand that you have misunderstood how this part of the truss works.

I don't think either I or the craftsman are hurt. I think we're trying to get you to understand that you've misunderstood how this part of the truss works.
Isn't it you who have misunderstood the picture then?

Does this make it easier??

The beam is not attached as in your sketch according to TS
 
In principle, the picture is correct, but the joints that are supposed to take up the torques m1 and m2 are so weak that they have no practical significance.
