Yes, there's a large mushroom shaped ferrule that the cable end fits into and goes into that big hole in the lever. Ask your bike shop for one. The Bell brake/shifter cable kits available in department stores also come with two of them.
Edit: Oh wait... You said aero levers? In that case, I don't know. They might, but then I've never had aero levers, just regular Dia Compe/ Weinmann non-aeros.
