We study the constraints on flavour violating terms in low energy SUSY coming from several processes as l i → l j γ, l i → l j l j l j and µ → e in N uclei. We show that a combined analysis of these processes allows us to extract additional information with respect to an individual analysis of all the processes. In particular, it makes possible to put bounds on sectors previously unconstrained by l i → l j γ. We perform the analysis both in the mass eigenstate and in the mass insertion approximations clarifying the limit of applicability of these approximations.
