Will this Belkin splitter work securely on an ipad air with an Apple Smart Cover?

I tried a different brand of splitter and the thickness of the Smart Case prevented the splitter from fully seating in the audio port. The plastic body of the splitter was too wide to fit through the opening cut in the Smart Case.

So, my question is, will the body of the Belkin splitter fit through the opening in an Apple Smart Case, so the jack can fully engage?
