3 x M12 nut & bolts at either end of the prop shaft. When the car is up in the air, you might want to allow for being able to turn a back wheel to get at all bolts. Sod's law will say that one of them will be right at the top where you can't get to it.

Thanks - so I'm basically going to take the prop shaft off completely ....

No. Drop it at the diff

But ......by the time you've tied the free end of the prop up, you could've undone the other 3 bolts & not have to worry if the prop will break free & fall to the ground enroute

It won't fall to much holding it up
Plus it won't turn only the diff will and it wont be connected to the prop

That's why it's being disconnected

Is it worth suggesting that flanges are marked, especially if the prop-shaft is completely removed. Then refitting in the same postion will reduce the risk of out-of-balance vibrations

I recently had to tow my 2.0 litre omega auto and was advised  by auto gearbox specialist that i could tow my car at a maximum speed of 20 mph for a distance of no more than five miles without disconnecting the prop, we followed these instructions and the gearbox was fine.

Vauxhall Book says 50mph for 60 miles

please excuse me for sounding dumb, could someone tell me why you have disconnect prop for towing. but what really confuses me is that is- isn't the prop what powers the drive. if thats disconnected whats powering the back wheels. sorry for being ignorant but if you don't ask you never find out..

this is for being towed, not towing to be more precise 

the wheels spinning madly, driving gearbox when being towed kills the auto gearbox, so disconnect the prop, then the gearbox isnt being driven

Yes, the prop does power the back wheels but via the gearbox via the engine. If your engine isn't running, you're not powering the back wheels 
In normal running, your geabox is turned by the engine, which drives a lub pump inside the autobox to lubricate it. If you're towing it, the gearbox doesn't get lub'd ..... resulting in a dead g/box.
What's powering the back wheels of the towed car? .... The tow car up front

Ah! I now understand the confusion ....
