A hitch adapted to be installed in the bed of a pickup truck and adapted to interlock with the kingpin of a fifth wheel trailer in order to couple the trailer to the truck. The hitch includes a pivoted latching plate for securing the kingpin, a reciprocating locking bolt for holding the latch in a latched position and a pivoted detent link for holding the locking bolt in an unlocked position when the trailer is uncoupled from the truck. When the trailer is subsequently re-coupled to the truck, the latch automatically trips the detent link to allow the locking bolt to shift automatically to a locked position holding the latch in a latched position.
