La présente invention concerne un assemblage d'une borne mâle et d'une borne femelle (100), la borne femelle (100) étant constituée d'un corps allongé en forme de boîte comprenant : - une ouverture frontale (108) pour l'insertion de la borne mâle et - un axe longitudinal qui se propage le long de la dimension la plus longue du corps allongé, et une largeur transversale à l'axe longitudinal, - un point de contact (112) qui rencontre la borne mâle par frottement et - un bras de retenue (126) qui rencontre la borne mâle par frottement. Le point de contact (112) et le bras de retenue (126) sont espacés l'un de l'autre dans un sens de la largeur. Le point de contact (112) avec la borne mâle est le point de contact le plus en avant entre la borne mâle et la borne femelle (100) le long de la ligne le long de laquelle le point de contact (112) rencontre la borne mâle.
