Holding device for holding a pair of rigid power lines in a spaced manner

A method for fastening a pair of rigid power lines of rectangular cross-section in a vehicle, the method comprising:

• arranging the pair of rigid power lines on the abutment surfaces of a holding device including:
• a fixing unit for fixing the holding device;
• a holding unit for holding the power lines to the holding device;
• wherein the holding unit comprises an inner-rib bar element and an inner-rib holding element, both of which are arranged between a first power line path predetermined for the first power line of the pair and a second power line path predetermined for the second power line of the pair;
• wherein the inner-rib bar element has a main extension plane which is transverse to the power line paths;
• wherein the inner-rib holding element is arranged along a common main extension direction of the inner-rib holding element and of the inner-rib bar element on the inner-rib bar element;
• wherein the inner-rib holding element has, along the main extension direction, at least a first section with a first abutment surface designed to abut against the first power line and at least a second section with a second abutment surface designed to abut against the second power line;
• and
• wherein the inner-rib holding element is arranged in the first section at a predetermined minimum distance greater than zero from the second power line path and is arranged in the second section at a predetermined minimum distance greater than zero from the first power line path;
• respectively closing at least one cable tie around the pair of power lines and the holding unit of the holding device and thus pressing the power lines against the holding unit by the respective cable tie;
• and
• fastening the holding device to the vehicle.
