An attachment section (100), in particular a brush section, suitable for connection to a handle section (200) of an oral hygiene device is proposed. The attachment section (100) has an attachment housing (150) having a first coupling structure (152) suitable for establishing a connection with a second coupling structure of the handle section, at least a functional element (130) mounted at the attachment housing (150) for driven movement, a motion transmitter (110) extending in a cavity formed inside of the attachment housing (150), the motion transmitter (110) being functionally connected on one end with the functional element (130), and a first magnetic coupling element (120) arranged at another end of the motion transmitter (110), the first magnetic coupling element (120) comprising at least a permanent magnet or a magnetizable element suitable for establishing a magnetic connection with a second magnetic coupling element provided in the handle section.
