  A few years ago the use of standard functional manipulations was demonstrated
to imply an unexpected property satisfied by the fermionic Green's functions of
QCD, and called effective locality. This feature of QCD is non-perturbative as
it results from a full integration of the gluonic degrees of freedom. In this
paper, at eikonal and quenching approximation at least, the relation of
effective locality to dynamical chiral symmetry breaking is examined.
