TERMS_AND_CONDITIONS Field Multi Language

Please,
Could you give an exemple for substitution. What do we have to write in language key.
I want replace in fr-FR plugin CONNEXION by S'IDENTIFIER.
If I write CONNEXION in clé (key) field and S'IDENTIFIER in texte field, it doesn't work.

Add a language override to the fr-FR plugin. You can use language overrides in any CB language plugin by editing the language plugin in CB > Plugin Management and clicking its Overrides tab. Use the built in search feature to find language keys.

Thanks,
I made these overrides :
CONNECTION_c2cc70 : S'IDENTIFIER (instead of Connexion)
LOGIN_99dea7 :S'IDENTIFIER (instead of Connexion)
CB_LOGIN : S'IDENTIFIER (instead of Connexion)
But no result as you can see on the photo.
In another, we don(t have the same list of language keys.
It seems it is a particular case.

I've no idea what "Connexion" is or where it's coming from. Looks like it's your module title that you've set in your module in Extensions > Modules. CB cannot translate module titles. You have to use Joomla language overrides for that.
