Claim Text:
1. A filler system of a tank of a motor vehicle, comprising: a pipe, the pipe including an upper pipe section and a lower pipe section, wherein a cross-section of the upper pipe section widens in a conical manner in a direction of an opening at an end of the upper pipe section opposite the lower pipe section; an upper filling opening at a lower end of the upper pipe section; a lower sealing flap arranged in the lower pipe section; a closing mechanism arranged above the upper filling opening and configured to prevent insertion of a fuel nozzle without opening the closing mechanism; and a pipe connection configured to connect the lower pipe section to a tank filler neck leading to the tank of the motor vehicle, wherein the tank filler neck is disposed between the lower pipe section and the tank of the motor vehicle when the lower pipe section is connected to the tank filler neck, wherein the pipe connection is designed to be released using a special tool specifically designed for the purpose of releasing the pipe connection and disengaging the lower pipe section from the tank filler neck, wherein attempting to release the pipe connection without using the special tool will result in destruction of the pipe connection, wherein the pipe connection is formed by resilient holding elements that are arranged between an end of the tank filler neck and the pipe connection, and wherein the resilient holding elements are configured to be displaced when the end of the tank filler neck is slid into the pipe connection, wherein holding edges of the resilient holding elements are configured to resiliently engage with respective accommodations to form a positive connection and being designed such that the holding edges wedge automatically in response to a stress in a direction of attempting to pull the pipe connection off the end of the tank filler neck, and wherein the resilient holding elements are configured to engage in recesses located proximate to the end of the tank filler neck during or after pushing or screwing the pipe connection onto the end of the tank filler neck and are configured to be retracted from the recesses using the special tool.
