  Higgs pair production is studied in the extension of the Standard Model by
color octet scalar and vector particles in TeV mass range for the LHC. The
relevant parameters are their masses and portal couplings to the Higgs
boson.The rate is enhanced considerably in some parts of the parameter space
compared to the SM which are allowed by the latest measured bounds on the Higgs
decay to $ZZ^*$. The model will be tested experimentally at the upcoming LHC
run.
