Usually with electrical connectors they call it based on the pins, unless it has both kinds of pins in which case they call it by the housing.
Anyways, so going off this picture, you're saying I can replace the female boots easily, by just removing the c-clip and sliding them off?
My headlight connectors on the truck-side wiring harness (as opposed to the headlight-side) are the ones I found splitting, so those are "female" (according to this picture). And I found that picture at multiple sources, so I'm guessing it's the proper naming convention for these.
