<p>A number of u-shaped clips with barbs at their ends are attached to a vertical bar (5) with a curved lower end (5b) leading into a housing (2) provided with a stick-shaped handle (10) on top. The housing (2) is positioned with a curved recess (21) located at its lower edge on top of the tube lying on an insulated base. When the spring supported shaft (10, 12) is pushed down using the transversal grip (11), a hook-shaped holding element is rotated through an opening (25) at the back of the housing (2) releasing the first of the clips which is axially moved by a sliding element and its barbs pushed into the material of the base.</p> |
