A cleaning arrangement for cleaning a vehicle window, comprising:
- a wiper arm;
- and
- at least one hose, fastened to the wiper arm, for a cleaning fluid,
- wherein the hose is connected by a form-fitting fastening, secure with regard to rotation angle relative to the wiper arm, at least indirectly to the wiper arm,
- wherein the hose comprises:
- a first region which is non-circular in cross-section, the first region being formed by two flat outer wall sections arranged at an angle with respect to one another, and

A cleaning arrangement for cleaning a vehicle window, comprising:
- a wiper arm having a first U-shaped cross section;
- at least one hose, fastened to the wiper arm, for transporting a cleaning fluid;
- and
- a shaped part,
- wherein the hose is connected by a form-fitting fastening, secure with regard to rotation angle relative to the wiper arm, indirectly to the wiper arm,
- wherein the shaped part is separate from the wiper arm and has a second U-shaped cross section, and comprises two grooves which comprise two parallel walls, which are disposed on an outer face of the second U-shaped cross section of the shaped part, and which extend in a longitudinal direction,
- wherein the first U-shaped cross section and the second U-shaped cross section are complementary to each other and are open to an identical direction, such that an entire top surface of the shaped part is flush with a bottom surface of the wiper arm, wherein the top surface extends in a lateral direction along the entire lateral length of an internal opening of the wiper arm,
- wherein inwardly projecting sections of the first U-shaped cross section of the wiper arm extend from terminal ends of the first U-shaped cross section of the wiper arm inwards, and engage into the grooves in positively locking fashion and fix the shaped part to the wiper arm in a direction, and
