A connection device for connecting at least two electric cables to an electric machine in a vehicle includes a housing and at least two contact elements. At least two openings, each allowing the passage of one of the cables, are located in the housing wall in such a way that only one of the cables that are fed in a direction through the openings in the housing and that continue to run in a straight line in the direction inside the housing makes direct contact with precisely one of the contact elements and can be electrically connected to this contact. All the other cables can be connected to a respective element of the remaining contact elements using a respective conductor bar.
