The main purpose of this paper is to study when a (T, I, D) construction ring is a C-ring in the sense of Echi (Port Math 50:277-95, 1993) where I is not necessarily a maximal ideal of T. This study allows us to generalize some results proved in Echi (Port Math 50:13-3, 1994) and to give new examples of C-rings.
