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-1 of data collected in p anti-p collisions at sqrt
s = 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/c2 and 109
GeV/c2, respectively. In the degenerate case, we exclude H+/-+/- mass
below 146 GeV/c2. All limits are quoted at the 95% confidence level.
