Device has removable rods with slanting bevels on front ends, positioned between circular conical shoulder of casing removable portion and a flexible member before the flange of casing supporting portion. Rods are installed in longitudinal grooves of casing supporting portion with a provision for being pressed down by a power member. Besides, each removable rod has an additional slanting bevel on its rear end, running parallel with main slanting bevel. Rods are rigidly fixed due to sliding of the lower edge of additional slanting bevel over conical surface of casing supporting portion until they come to bear against the flexible member and the side surface of the groove in the flange of the casing supporting portion.
