Renormalized triple gauge vertices (TGV) are examined within the two-Higgs-doublet model of the electroweak interactions. Deviations of the TGV from their standard-model values are calculated at the one-loop level, in the on-shell renormalization scheme. As a consistency check, UV divergence cancellations anticipated on symmetry grounds are verified explicitly. The dependence of the TGV finite parts on the masses of possible heavy Higgs scalars is discussed briefly.
