The housing base part and the attachment part are made of rectangular sheet metal pre-cut parts by notching and bending processes. The housing base part has two arms (11) that are parallel to each other and spaced apart by a rear wall (12). The arms have chamfers (13) that are spaced apart by slit-like notches (14), at three sides. The attachment part has a front chamfer (21) and a rear chamfer (23).
