The connectors you see in the image are known as spade connectors, also push-on spade connectors, typically in insulated and non-insulated forms.
The above Amazon link is but one of many sources. Harbor Freight has available for purchase a few assortments of terminal connectors. For small quantities, at proportional higher prices, one can certainly find these spade connectors at local auto parts stores. I have three stores within two miles and all of them carry various sizes of the connector, both male and female connections.

You'll probably find that you can only buy matched sets, if you need only the two. Maybe a box of six, three of each, at an auto parts store. Check the wire gauge you plan to use and match that with the legend on the box.
