Abstract
A gooseneck hitch is latched to a trailer platform by a pin which may be shifted linearly to an unlatched position against the bias of a spring so as to permit removal of the gooseneck from the platform. A first detent unit holds the latch pin in its unlatched position once the pin has been moved to that position and as long as the gooseneck remains in an installed position on the platform. As the gooseneck is removed from the platform, a second detent unit releases the first detent unit from the latch pin but continues to hold the latch pin in its unlatched position. Upon re-installation of the gooseneck, the second detent unit is automatically released from the pin and permits the spring to automatically shift the pin to its latched position.
