The first limit on the branching ratio of the electric charge-nonconserving invisible muon decay Br({mu}{sup +}{yields}invisible)<5.2x10{sup -3} is obtained from the recently reported results on new determination of the Fermi constant from muon decays. The results of a feasibility study of a new proposed experiment for a sensitive search for this decay mode at the level of a few parts in 10{sup 11} are presented. Constrains on the {tau}{yields}invisible decay rate are discussed. These leptonic charge-nonconserving processes may hold in four-dimensional world in models with infinite extra dimensions, thus making their searches complementary to collider experiments probing new physics.
