The wall coupling incorporates a tubular component (4) with an open and externally threaded end part (5) for fixture to the respective threaded connecting point (3). Arranged with the opposite free end part (6) is a closed component (4) with an outer diameter matched to the connecting component of the wall plate. After installation, the component (4) is cut to a length matching the wall plate used. Preferably, the component free end part (6) permits tool engagement facilitating the installation of the component. The component external threaded end part (5) can be eccentrically displaced in relation to the component central longitudinal axis for permitting the matching of the component reciprocal central distance to a distance relative to the internally threaded fastening points (3) reciprocal distance. |
