Let G be a simple graph. A t-uniform homeomorph Pt(G) of G is the graph obtained by replacing all edges of G by vertex disjoint paths of length t. In this paper we show that (1) Pt(K2n) is cordial. (2) Pt(K2n+1 is cordial iff either n, t both have same parity or one of them is equiv 2 ( mod 4) and the other is odd.
