We consider subsets G of a generalized effect algebra E with 0∈ G and such that every interval [0, q ] G = [0, q ] E ∩ G of G ( q ∈ G , q ≠ 0) is a sub-effect algebra of the effect algebra [0, q ] E . We give a condition on E and G under which every such G is a sub-generalized effect algebra of E .
