  Tunneling of fractionally charged quasi-particles (QPs) through a barrier is
considered in the context of a multiply connected geometry. In this geometry
global constraints do not prohibit such a tunneling process. The tunneling
amplitude is evaluated and the crossover from mesoscopic QP-dominated to
electron-dominated tunneling as the system's size is increased is found. The
presence of disorder enhances both electron and QP tunneling rates.
