What is that tube on the left side panel?

... and why is it ending hanging freely with open end ...?

I think there is a wire that should go in that tube, it has something to do with the ejection iirc, might be connected to the legs?

Checked my pictures and found a pic with the real deal

 

Looks a bit different, sure looks like some sort of protection or some cable should go through it

It's a part of the ejection system. It holds a rope that is connected to a net that pull the arms in toward the seat in the case of an ejection, so the arms are flailing around in way you really don't want them to do.
