Abstract
The invention relates to a covering placed against the housing wall by means of a self-adhesive coating applied to the underside of the covering and covers the recess provided in the housing wall. An inner opening passing through to the inside of the housing is provided in the recess. A gas-permeable, however fluid-impermeable, diaphragm is glued over the inner opening. The adhesive coating applied to the underside of the covering is discontinuous in the area of the inner opening in order not to close the pores of the diaphragm. The outer opening is situated so that it is laterally offset from the inner opening, and is made in the covering while being completely delimited thereby.
