A system that uses the male-female coupling concept, by mechanical interference between the serrated toothing on the parts to be fastened permanently together or by way of a sleeve-like couplings, but not before sealing elements which satisfy the IP 68 rating are placed therebetween. The outermost, female part or the sleeve-like couplings have particularly elastic peripheral ribs which allow them to expand sufficiently to fit the serrated toothing, such that the mounting can only be undone by cutting the rib, thus characterizing the violation of the sleeve-like coupling or of the outermost female part having a complex profile, used in the fastening system.
