1. A polymer tube for detecting a pipe buried underground, said tube comprising:
- the polymer tube;
a plurality of radio-tags arranged at regular intervals along the tube; and
a protective layer of said tags;
wherein each of said radio-tags comprise a resonant circuit split into interconnected subassemblies of low inductance, so that the resulting resonant circuit has an increased capacitive value being less sensitive to the stray capacitances present depending of the permittivity of the environment, in particular in a moist environment.
