We present numerical results for the electrical conductance G of normal disordered loops containing two superconducting islands and show that G has a periodic dependence on the phase difference between the superconducting order parameters of the islands. At low energy E, the ensemble averaged conductance possesses a periodicity of 2pi, which crosses over to a periodicity of pi with increasing E.
