The mechanical sealing and dosing loop comprises a spindle drive, the spindle (1) of which moves a spindle nut (2) located on it, whereby the spindle nut opens or closes a loop (4) guided in a shoe (3) according to the direction of rotation of the spindle. A hand-grip (5) is fastened to the spindle nut and transmits the torsional forces arising through the movement to the counterstop on the operator.
