A novel interconnection of the jaw, wedge and operating handle in a fifth wheel facilitates the provision of a secondary locking mechanism which further insures the security of the system. In the invention, the jaw is connected to the operating handle by a pivoting timing lever which pivots off a pin on the jaw such that the jaw remains engaged with the fifth wheel until the wedge is substantially removed from engagement with the jaw. In cooperation with the primary locking mechanism, a secondary lock is provided at the end of the operating handle such that a pin arrangement engages a stop on the fifth wheel assembly until positively released by the operator.
