Gaz regulator?

[The Robbo's]

Hi.
I've bought a camping gaz 907 specifically to use with a 2 burner stove in the drive away awning.
Which is the best way to disconnect the stove from the bottle when traveling.
Would it be ok to leave the regulator connected on the bottle & remove the hose or keep unscrewing the regulator.
Just concerned if the regulator get knocked etc in an accident whilst it's not connected to anything other than the bottle.

I unscrew the regulator and put the screw cap back into the bottle. -- (thats the way i do it I expect some leave it in the bottle).
I also always when driving turn the valve off at the bottle on the bottle in the van when traveling I know othere leave it turned on all the time

I also find in easier to get someone to hold the regulator and rotate the gaz bottle off
