In this paper, we estalibsh the existence and uniqueness of fixed point for T -quasi contractive of Ciric type in Sb-metric spaces. These results extend and generalize well-known results in documents of L. B. Ciric (Proc. Amer. Math. Soc,1971), S. Sedghi, N. Shobe, A. Aliouche (Math. Vesik, 2012), S.
Sedghi, N. V. Dung (Math. Vesik, 2014).
