A mounting arrangement of a suction nipple on a vacuum cleaner includes an elongated portion of the suction nipple inserted into an opening formed in a housing of the vacuum cleaner. The elongated portion is provided with two vertically spaced bearing surfaces arranged in contact with the housing and forming a clearance in an area therebetween. A lower end of the elongated portion is supported by an elastic sealing ring. The elastic ring is formed with projections extending into the grooves made in the housing to seal the mounting arrangement. |
