ABSTRACT:
A fastening arrangement of a pipe is provided. The fastening arrangement is coaxial to a longitudinal axis, on a shaft step, which is rotatably mounted around the longitudinal axis, for connecting of the two component parts, with a coaxial circumferential surface located on the shaft step, upon which circumferential surface at least partially lies the inner side of the pipe end which faces the shaft step. In order to disclose the creation of a fastening arrangement which is especially simple and inexpensive to manufacture and also free of wear during operation, it is proposed that the pipe end has notches distributed over the circumference, and an encompassing annular slot on the inner side of the pipe in the region of the notches, with a sleeve which is installed in the annular slot, covers the notches, and at least partially lies on the circumferential surface of the shaft step.
