  The recent detection of $\gamma$-rays with energy up to 10 TeV from dense
regions surrounding some Supernova Remnants (SNR) provides strong, though still
not conclusive, evidence that the nucleonic component of galactic Cosmic Rays
is accelerated in the supernova outflows. Neutrino telescopes could further
support the validity of such scenario by detecting neutrinos coming from the
same regions. We re-evaluate the TeV range neutrino-photon flux ratio to be
expected from pion decay, finding small differences respect to previous
derivations. We apply our results and the recent HESS measurements of the very
high energy $\gamma$-ray flux from the molecular cloud complex in the Galactic
Centre, to estimate the neutrino flux from that region discussing the
detectability perspectives for Mediterranean Neutrino Telescopes. We also
discuss under which conditions neutron decay may give rise to a significant TeV
antineutrino flux from a SNR embedded in Molecular Cloud complexes.
