We study unconventional signatures of the NMSSM (the MSSM with an additional gauge singlet) with a singlino LSP. Compared to sparticle production processes in the MSSM, these consist in additional cascades (one or two additional l+ l-, tau+ tau- or b bbar pairs or photons), possibly with macroscopically displaced vertices with distances varying from millimeters to several meters.
