  A search for pair-produced charged Higgs bosons was performed in the data
collected by the DELPHI detector at LEP II at centre-of-mass energies from 189
GeV to 209 GeV. Five different final states, tau+ nu_tau tau- anti-nu_tau, c
sbar cbar s, c sbar tau- anti-nu_tau, W* A W* A and W* A tau- anti-nu_tau were
considered, accounting for the major expected decays in type I and type II Two
Higgs Doublet Models. No significant excess of data compared to the expected
Standard Model processes was observed. The existence of a charged Higgs boson
with mass lower than 76.7 GeV/c^2 (type I) or 74.4 GeV/c^2 (type II) is
excluded at the 95% confidence level, for a wide range of the model parameters.
Model independent cross-section limits have also been calculated.
