Adjustment components are arranged on a stirrup (2) for varying its width and height so that it can be set with force against the casing. Via anchoring components in the base, the apparatus is locked firmly to the base (3) on which the apparatus rests. The stirrup comprises first and second coupling parts (4, 4') with axially displaceable tube or channel-shaped parts forming the legs (5, 5') and upper part (6) of the stirrup construction. One of the coupling parts has an access aperture for reaching the adjustment components for varying the width of the stirrup construction and a further access aperture for reaching the adjustment components for varying the height of the stirrup construction. |
