It is proved that characteristic forms generate, over $\Omega^{\bullet}(M)$, the algebra of differential forms on the bundle of connections $p\colon C(P)\rightarrow M$ of a principal $G$-bundle $\pi\colon P\rightarrow M$ which are invariant under the natural representation of the gauge algebra of $P$ on connections. The invariance under the Lie algebra of all infinitesimal automorphisms of $P$ is also analyzed.
