Une section inférieure (8.1) de la borne de batterie (8) comporte dans le plan de coupe horizontal un diamètre plus petit qu'une section supérieure (8.2) reliée à la section inférieure (8.1) de la borne de batterie (8), de telle sorte que la section supérieure (8.2) de la borne de batterie (8) comporte une face inférieure (8.2.2) en saillie par rapport à la section inférieure (8.1). La section supérieure (8.2) de la borne de batterie (8) comporte au moins une rainure (8.2.1) s'étendant dans l'extension verticale (R) de la borne de batterie (8) pour diriger un élément de forme (5.4) de l'élément de raccordement (4) de la section supérieure (8.2) vers la section inférieure (8.1). Une surface de la section supérieure (8.2) est réalisée de manière sensiblement symétrique en rotation. La face inférieure (8.2.2) comprend au moins une zone en forme de rampe qui, à partir d'au moins une rainure (8.2.1) et par rapport à un sens de rotation (D) autour d'un axe vertical de la borne de batterie (8), est formée croissante en allant vers le bas. L'élément de raccordement peut être fixé au moyen de l'élément de forme (5.4) par rotation dans le sens de rotation (D) sur la face inférieure (8.2.2) de manière à assurer la liaison par le serrage de l'élément de forme (5.4) par rapport à la zone en forme de rampe suite à la rotation. L'invention concerne en outre un dispositif de contact et un élément de raccordement (4) pour un tel dispositif de contact et une batterie (9) avec une borne correspondante (8).
