Fixing device for detachably fixing a body to a motor vehicle, and luggage-carrying device

An apparatus comprising:

• at least one fixing device that includes at least one first fixing half and at least one second fixing half, wherein the at least one first fixing half is fixed to a luggage container, and the at least one second fixing half is fixed to a load-bearing vehicle component of a motor vehicle and which is detachably joined to the first fixing half in a coupled arrangement in order to fix the luggage container to the vehicle component;
• and
• at least one electrical line which is guided from the vehicle component to the luggage container and is fixed to the luggage container in order to supply an electrical load, wherein
• the first fixing half comprises a first conductor of the electrical line and the second fixing half comprises a second conductor of the electrical line, and
• the first conductor and the second conductor are electrically conductively connectable or are electrically conductively connected to one another in the coupled arrangement of the first and second fixing devices, wherein
• the first fixing half includes a first coupling element, and the second fixing half includes a second coupling element,
• the first coupling element comprises a snap-in member, which is configured to join the second coupling element to the first coupling element,
• the snap-in member being movable across the wire at an angle to the joining direction,
• the snap-in member being configured to fit into a recess of the second coupling element, at which location the snap-in member is snapped transversely or obliquely to the joining direction,
• an end of the first fixing half forms a rear grip and accommodates therein the first conductor of the electrical line, and
• the luggage container is fixed to the motor vehicle exclusively via the at least one fixing device.
