We investigate the two-body non-leptonic decays of doubly charm strange, , baryon. The branching ratios of the baryon decays involving a pseudoscalar meson for CKM-favored and -suppressed modes are determined by employing the pole model and the factorization hypothesis. We give the first estimates of the non-factorizable W-exchange contributions of decay in the pole model. We find that the branching ratios of some decays receive contributions, exclusively from the W-exchange diagrams, are as large as 
. The non-spectator contributions in doubly charmed decays are comparable to the factorizable contributions in most of the cases.
