kingpin to prevent unlawful coupling and removal has been designed by Ellis (Colchester).
It can be easily fitted with one hand, says the company, and when it is locked in position, by pushing the lock button, it rotates about the pin making it difficult to attack with drills and hammers, etc.
It is unlocked with a key and simply slides from the pin into the driver's hand.
The body of the device is machined from thick-walled seamless tubing and the lock is let-into and welded to it. The push button incorporates an anti-drill device giving additional lock protection.
Price: £20.
Made by: Ellis (Colchester) Ltd, Commerce Way, Whitehall Road, Colchester, Essex.
