I have looked at your frame and tried to match it to Gitane frames with a date code serial number.

The Tour de France head tube lugs changed during the early 1970s.

I found a match with the same decals and head tube lugs. That frame was dated as week 3 of year 1973.

You can see that Gitane Tour de France on another forum's thread:
