  We propose here a new discretization method for a class continuum gauge
theories which action functionnals are polynomials of the curvature. Based on
the notion of holonomy, this discretization procedure appears gauge-invariant
for discretized analogs of Yang-Mills theories, and hence gauge-fixing is fully
rigorous for these discretized action functionnals. Heuristic parts are
forwarded to the quantization procedure via Feynman integrals and the meaning
of the heuristic infinite dimensional Lebesgue integral is questionned.
