L'invention concerne un dispositif de connexion mâle-femelle permettant un raccordement électrique automatique, c.-à-d. multipolaire d'une remorque de véhicule, notamment un semi-remorque, à un véhicule de traction, notamment un tracteur de semi-remorque. Ledit dispositif comprend une prise de courant (D) et un connecteur (S), qui peuvent être montés sur la remorque du véhicule (par ex. le connecteur S) ou le véhicule de traction (par ex. la prise de courant D) et peuvent être alignés l'un par rapport à l'autre lors de l'accouplement de la remorque au véhicule de traction et peuvent être déplacés de manière guidée, à l'aide d'un mécanisme d'entraînement (10) se présentant sous forme de système piston-cylindre, l'un par rapport à l'autre, entre une position de connexion (poussée vers l'avant) et une position de repos (en retrait). De préférence par ex. un couvercle (d) de la prise de courant (D) peut être ouvert par déplacement de la pièce de contact rapportée (1) logée dedans et portant les connecteurs femelles (11, 12), en direction de la position de connexion, à l'aide du mécanisme d'entraînement (10) et être refermé, lors du retrait de la pièce de contact rapportée (1) en position de repos. Ledit dispositif de connexion mâle-femelle se caractérise en ce que le connecteur (S) est monté de sorte à s'affaisser latéralement de manière élastique, à l'encontre de l'action d'au moins un ressort de retenue (213, 213'), fixé d'une part sur le connecteur (S) et d'autre part, sur un flasque de fixation (210) pouvant être fixé sur de véhicule (véhicule de traction ou remorque).
