A wiper arm comprises a coupling lever for fastening to a rotatable wiper shaft, a guiding lever for attaching a wiper blade, and a folding joint having a folding axis for connecting the guiding lever to the coupling lever. The coupling lever comprises a profiled element, which has a U-shaped cross-section, and a pin, which extends between the opposite legs of the profiled element. The wiper arm also comprises a spring element, which engages with the pin in order to apply a torque between the coupling lever and the guiding lever via the folding joint, and a hose line for conducting a liquid along the wiper arm. The hose line and the spring element are arranged in the profiled element of the coupling lever in the region of the folding joint.
