Abstract
Interengageable male-female style coupling device with a pivotally movable lock plate having an entrance/egress aperture with a tapered entering surface. The tapered surface both facilitates engagement of coupling members and acts to securely fasten the coupled members in locked position. The device is particularly suited for 'gooseneck' or 'neckover' coupling devices commonly used in tractor-trailers hauling.
