The paper treats the isometric deformability of non-simply-connected constant mean curvature surfaces which are neither assumed embedded nor complete. We prove that if a smooth oriented surface M immersed in R^3 admits a nontrivial isometric deformation with constant mean curvature H then every cycle in M has vanishing flux and, when H is not zero, also vanishing torque. The vanishing of all fluxes implies the existence of such an isometric deformation when H = 0. Our work generalizes to constant mean curvature surfaces a well-known rigidity result for minimal surfaces.
