The said joint is made in the form of a spring laid in the case groove interacting with the mating groove made in the rotor in closing. Here note, that the case is provided with a circular cylindrical groove equal in depth to, at least, the thickness of the embracing element the passive end of which is rigidly fastened in the case. Note here, that the rotor is provided with the holes to receive the ledges of the handle. The case is made in the form of a flat body with a cylindrical side surface. The seal is provided with the seal closed position indicator made in the form of two flat ledges aligned in closed position of the seal. The case rear has a seat for washer rigidly attached to the rotor and allowing the latter to turn through free in the case. ^ EFFECT: increased resistance against unauthorised opening. ^ 5 cl, 9 dwg
