A Hamming graph is a Cartesian product of complete graphs. The main results of the paper are: (i) a quasi-median graph without isometric rays contains a Hamming graph which is invariant under any automorphism; and (ii) any contraction of a rayless quasi-median graph stabilizes a finite Hamming graph.
