摘要

The device has a sealing clamp of two shell parts (2,2') that rotatably enclose a box nut and are destroyed if the nut is released. The shell parts are joined at at least one side with at least one protrusion on one engaging at least one aperture (32b,32b') on the other so they cannot be separated without damage. The two shell parts have at least one strengthening rib (8) extending in the radial inward direction to give enhanced shape stability.
