Le premier et le deuxième de ces éléments de connexion enfichable (12, 13) sont, dans l'état enfiché, électriquement reliés au premier ou au deuxième contact à tension continue (19, 20) par l'intermédiaire d'un premier et d'un deuxième ensembles ressorts (21, 24), sachant qu'au moins une diode (25) polarisée dans la direction de blocage relie entre eux les deux ensembles ressorts (21, 24). Au moins le premier ensemble ressort (21) est constitué de deux zones partielles (22, 23), la première zone partielle (22) étant reliée en permanence à la diode (25) et s'appliquant élastiquement contre le premier élément de connexion enfichable (12) dans l'état enfiché de celui-ci, et la deuxième zone partielle (23) reliant électriquement cet élément de connexion enfichable (12), dans l'état enfiché, au premier contact à tension continue (19). La deuxième zone partielle (23) est conçue pour ouvrir cette liaison électrique avant la suppression de l'application de la première zone partielle (22) contre le premier élément de connexion enfichable et avant la suppression de l'application du deuxième ensemble ressort (24) contre le deuxième élément de connexion enfichable (13) lors du débranchement.
