The frame has racing geometry, top tube cable tunnels and bottle bosses. It also appears to have 700C wheels and the derailleurs appear to be be the new style introduced by Huret in 1974. Consequently, it would appear to be mid to late 1970s but based on the cable tunnels and bottle bosses it should be firmly in the late 1970s and probably the very late 1970s.. I don't think it would get into the early 1980s based on the TA crankset.

The missing piece of the puzzle is the tubeset. Check to see if there is a size stamped on the seat post. if not and you have a set of calipers. measure the diameter. That should give us a good idea of the tubing grade. However, it would appear to be at least mid-grade based on the frame fittings. The entry level models typically used cable stops and didn't have bottle bosses during the apparent era.
