FIELD: personal use articles.SUBSTANCE: group of inventions includes a nozzle, in particular a brush section, suitable for connecting it to a handle of the hygienic device for oral care (variants), the handle of the hygienic device for oral care for connection, including the removable attachment, to the nozzle, and a hygienic device for oral care, comprising a nozzle and a handle, relates to the field of medical devices and is intended for use in oral hygiene. The nozzle, in particular the brush section, suitable for connecting it to the handle of the hygienic device for oral care, comprises a nozzle body, a functional element, a device for transmitting motion, and a first magnetic coupling element. The nozzle body comprises a first coupling structure made with the ability to establish connection with the second structure of the handle coupling. At least one functional element is mounted in the nozzle body to make the movement from the actuator. The device for transmitting motion is made extended in the cavity formed inside the nozzle body, is operatively connected to the functional element at one end. The device for transmitting motion comprises a traction element pivotally connected to the functional element. The first magnetic coupling element is located at the second end of the device for transmitting motion and comprises at least a permanent magnet or a magnetisable element made with the ability to establish magnetic coupling with the second magnetic coupling element, provided in the handle.EFFECT: inventions enable to create an improved coupling structure between the nozzle and the handle of the hygienic device for oral care due to magnetic coupling.14 cl, 12 dwgГруппа изобретений включает насадку, в частности щеточную секцию, подходящую для присоединения ее к рукоятке гигиенического устройства для ухода за полостью рта (варианты), рукоятку гигиенического устройства для ухода за полостью рта для присоединения, в том числе съемного присоединения, к насадке и
