La présente invention concerne une fiche et une prise femelle qui sont conçues respectivement pour pouvoir être connectées à un câble thermique codé protégé contre l'inversion de polarité. La fiche et la prise femelle comprennent respectivement un logement qui sert à loger en le protégeant contre l'inversion de polarité un câble thermique dont la section transversale est asymétrique, et un premier et un deuxième élément de fiche ou de prise femelle électriquement conducteur qui comportent respectivement une première et une deuxième zone. La première zone des éléments de fiche ou de prise femelle comporte respectivement un contact à ressort et les éléments de fiche ou de prise femelle sont agencés de telle sorte que les deux contacts à ressort entrent respectivement en contact sensiblement axialement avec un fil électrique d'un câble thermique logé.
