An entry slot for retention of a bottle (8) is formed at an area of a C-shaped annular bracket (6) lying opposite to a bolt (5). Size of the slot is smaller than diameter of the bracket. A support (4) of the side piece is provided for arranging and pivotably holding the bolt in the support. The diameter of the bracket corresponds to diameter of the bottle. The bolt is vertically removed and inserted into the support.
