I've got exactly the same problem, what a weird way to secure a battery conection!.....

Think I managed to get it on as securely as it needs to be, it's pretty tight.
Socket would've been my next port of call but I would've had to buy a socket set, not completely out of the question but it was more the time (really needed it working by tonight if possible!)
If anyone knows of an easy "official" way to get it off then I'm all ears... I'm glad it doesn't look like it's just me being a complete moron though
Eventually I managed to undo the nuts at the top but that hasn't made any difference, plate is still in the way. Whilst doing this, the connector didn't move as you had experienced, but the plate started bending and would have snapped off if I didn't hold it in place with an adjustable spanner grip.
A socket set doesn't help, you just can't get to that nut with a socket as the plate is completely in the way.

Don't move that, use an open ended wrench (crescent spanner) on the hex nut at the other end of that bolt, that will open the clamp and allow you to take the block off of the battery terminal.
Yes that is the nut that needs to be undone, but it is impossible to get an open ended wrench at that, look at the gap on the left hand side of it, it is about 1mm, you can't get a wrench around both sides of the nut. The gap on the right hand side is also small so can't get a wrench hooked around there.
Any ideas please?!
