A statement said the two officials, who had been widely tipped for the posts, were elected by acclamation during an executive committee meeting in Bahrain.
They succeed Guinean Almamy Kabele Camara and Suketu Patel, a Seychellois who quit CAF in March after long-serving Issa Hayatou of Cameroon suffered a shock presidential election defeat.
It was the first meeting of the executive since Madagascan Ahmad Ahmad beat Hayatou 34-20 in a vote for the top CAF post.
Manama, the capital of Middle East state Bahrain, also plays host to meetings of world football organisation FIFA this week.
