They do different types for different hitches. What i especially like about this is that it can stay on when towing too.
it’s for a boatMate had his caravan stolen despite Al-Ko locking hitch, decent wheel clamp and door clamp. Thieves simply changed the hitch and left the old, locked, one behind ! The wheel clamp was cut off with Stihl saw and again left. Since then mate has always had a tracker fitted to his caravans and doesn't bother about other security as he knows "if they want it they will find a way". All you can do is slow down the theft to the point where thieves realise it will take too long and therefore more chance of getting caught. With that in mind I'd say go for belt and braces approach - wheel clamp on both wheels, locking hitch plus a locking hitch cover, chain trailer to something solid if possible and consider a tracker just in case the worse happened.
