The plant is Huernia zebrina N.E.Br. As stated it belongs to the family Apocynaceae (or formerly to Asclepidaceae) and therefore is not a true cactus, should be called succulent instead. It is by family related to the genus Hoya. This species grows in eastern South Africa in mostly stony areas, preferrably calcrete or hard loam.
ID from the book "Stapeliads of Southern Africa and Madagascar" vol 1 by Peter V. Bruyns. A great book if you are interested in succulent "Asclepiads".
