300tdi engine bay fuse box - cant work out disconnection

Its a rubbish question - im sure i should be able to work it out, but i cant.

Is it one of those ones where you have to stick a screwdriver in and bend pins?

Basically, i need the loom on the other side of the bulkhead, so as i can remove it from the vehical, and fit it to my new bulkhead. This fuse box is one of the few remaining things stopping me - i think!

This one -



That picture makes it look as if there's screw terminals, but im sure i did not see any when i was tugging at it earlier?

Does this picture help?

I think I took it because I was concerned that I might slot it together the wrong way.
IIRC when you slip the cover off the fuse box you can disconnect it. Can't quite remember how though, so hope this helps!
