At the Large Hadron Collider, we prove the feasibility to detect pairproduction of the lightest CP-even Higgs boson h of a Type II 2-Higgs DoubletModel through the process q \bar q' --> Vhh (Higgs-strahlung, V=W+-,Z), inpresence of two h --> b \bar b decays. We also show that, through suchproduction and decay channels, one has direct access to the following Higgsself-couplings, thus enabling one to distinguish between a standard and theSupersymmetric version of the above model: lambda_(Hhh) -- which constrains theform of the Higgs potential -- as well as lambda_(W+- H+- h) and lambda_(Z A h)-- which are required by gauge invariance. Unfortunately, such claims cannot beextended to the Minimal Supersymmetric Standard Model, where the extraction ofthe same signals is impossible.
