The title "Mannesmann" will probably stand for German quality. But far from it !!! 1. Made in China 2. Quality miserable 3. For the purpose - to clamp hoses so totally unsuitable because even very low load durchdreht- the mounting screw and thus no resistance arises in the connection. 4. On the picture on Amazon was impossible to tell exactly how the worm driving is constructed. 5. The only thing you need in this article is the supplied wrench.
Conclusion: Who kauft- this product be money thrown out the window !!
