We present a search for long-lived doubly-charged Higgs bosons (H{sup {+-}{+-}}), with signatures of high ionization energy loss and muon-like penetration. We use 292 pb{sup -1} of data collected in p{bar p} collisions at {radical}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{sub L}{sup {+-}{+-}} and H{sub R}{sup {+-}{+-}} bosons with masses below 133 GeV/c{sup 2} and 109 GeV/c{sup 2}, respectively. In the degenerate case we exclude H{sup {+-}{+-}} mass below 146 GeV/c{sup 2}. All limits are quoted at the 95% confidence level.
