They don't use winglets on refueling drogues or hoses. They're just shuttlecock shaped.
They do put winglets on rigid refueling booms, however. Maybe that's what you were thinking of?

I don’t know what I was thinking of as I just remember seeing b&w film footage as a kid with some explanations by my Dad retired as a naval aviator once assigned to a drone squadron back in the day as remote controls led to joysticks when ‘gaming’ with real life.
Nice quick writeup with boom (high volume) and hose (low volume) pics here...
