We present a search for long-lived doubly-charged Higgs bosons (H^±±), with signatures of high ionization energy loss and muon-like penetration. We use 292/pb of data collected in p-pbar collisions at sqrts = 1.96 TeV by the CDF II detector at the Fermilab Tevatron. Observing no evidence of long-lived doubly-charged particle production, we exclude H^±±_L and H^±±_R bosons with masses below 133 GeV/c^2 and 109 GeV/c^2, respectively. In the degenerate case we exclude H^±± mass below 146 GeV/c^2. All limits are quoted at the 95
