Thanks for your pointer. Sadly the mpl.toolkits.axes_grid is not shipped
by debian package, and downloading it requires other stuff. So I adapted
from the inset_locator.py the attached file.

Finally I can "zoom" with the mere script :
        import matplotlib.pyplot as plt
        from mpl_axes_grid_inset_locator import zoom_effect
        S1 = plt.subplot(211)
        S1.plot(... # xlim  (0.,1.2)
        S2 = plt.subplot(223)
        S2.plot(... # xlim  (0.0095,.012)
        S3 = plt.subplot(224)
        S3.plot(... # xlim  (0.84,1.)
        # Labels stuff
        # [...]
        
        patch_props=dict(ec="r", alpha=0.5, fc="r")
        zoom_effect(S1,S2, 0.01, 0.011, **patch_props)
        zoom_effect(S1,S3, 0.90, 0.95, **patch_props)

It produces two zoom subplots with the wanted patch.
