You should never touch the default_language files of any plugin - your changes will be over-written when you update the add-on.
You need to make changes to your Russian language plugin cbplugin/cbconnect-admin_language.php and cbplugin/cbconnect-language.php files.
If you want to help with the translations please contact the Russian coordinator Alex here:
