Tyre inflator can holder

I saw a picture on here of someone's boot, and attached to the back of the rear seats was a holder for the two cans of tyre inflator. Does anyone know who's car it was or where you can buy the holder from? I'm fed up of it moving around in the boot all the time!
 
Mine sits in the glovebox, had one kept in the boot but went around a corner too fast and it blew up......that was a fun one to clean up!
 
Mine are in a case. Not seen a clip for them before.

I bought a cheap boot net, only a small one that fits on the side of the boot, mine sits in that and doesnt fly about!
 
I stuck a big bit of sticky backed velcro to the tin and stuck it in the front left hand corner stood upright on the boot floor. It never moved. Cheaper than buying anything else and the velcro comes in use for other stuff.
