We recalculate the leading one-loop contributions to μ eγ and μ eee̅ in the Littlest Higgs model with T-parity, recovering previous results for the former. When all the Goldstone interactions are taken into account, the latter is also ultraviolet finite. The present experimental limits on these processes require a somewhat heavy effective scale ∼ 2.5 TeV, or the flavour alignment of the Yukawa couplings of light and heavy leptons at the ∼ 10% level, or the splitting of heavy lepton masses to a similar precision. Present limits on τ decays set no bounds on the corresponding parameters involving the τ lepton.
