There is a drilling (8) in the casing (2) starting from one of the plane external surfaces, the peripheral surface of which intersects with the outside of the passage running along the extruded section. Here, the grooves (3) have undercuts and are especially T-, trapezoidally or dovetail-shaped, the aperture (9) of the groove (3) in the external surfaces (4, 5, 6, 7) having the smallest cross-sectional width. |
