The fluid coupling includes a ramp positioned to be engaged by one end of a trip member pivotable about a pin to thereby move another end of the trip member into engagement with said one portion and move the connector portion thereof out of engagement with the holding device in response to separation of the towing connection and relative separation of the tractor and towed equipment.
