摘要
A lock encircles the annular locking groove on the kingpin of a travel trailer of the semi-trailer type to prevent the kingpin from entering the receiving slot of the fifth wheel on a towing vehicle and includes locking collar halves each having a semi-annular body portion from the ends of which flanges extend radially outwardly. One flange on one half is S-shaped and has a hooked end engagable in a slot on a flange on the other half for releasably coupling the halves together with the remaining two flanges in abutting relation. These remaining two flanges may be provided with apertures adapted to receive a padlock hasp for locking the two halves together.
