  We present chemical abundances for Mg, Si, Ca and Fe for three red giants in
the sparse globular cluster Terzan 7, physically associated to the Sagittarius
Dwarf Spheroidal Galaxy (Sgr dSph), which is presently being tidally disrupted
by the Milky Way. The data has been obtained with VLT-UVES and show a mean
[Fe/H]=-0.57, with solar alpha content, mean [alpha/Fe]=-0.03. This enforces
Ter 7's membership to the Sgr dSph system, which shows a similar pattern of
abundance.
