Making loft from 2 curves

Hello everyone.

I’m trying to make a surface with the 2 curves shown, so they will make some sort of curved tube but I’m not sure how to go about doing it. I tried using the Loft component but it doesn’t seem to be doing anything.

Any help will be greatly appreciated.
Thank you very much in advance!
