Didier,
I can't read the "motto".... not a DI I've ever seen referenced.... the "Green Cross" is normally associated to Veterinary Corps... not medical. Interesting pin even if not a DI..... I like it.

It is Honneur et Discipline

I know that Honneur et Discipline is French Navy ,, and also French Penitentury (ah hell---prison motto)
