An identificant is insertable into an identificator, and carries a number of input points and a number of output points, certain of the input points being connected with certain of the output points in accordance with a predetermined code. The code does not use binary logic but rather a translation logic. The identificator comprises a number of input pins and a number of output pins, the input pins being engageable with the input points of the identificant, and the output pins being engageable with the output points of the identificant, more specifically with strip conductors connecting respective input points to respective output points. The input pins are connected to respective pulse generators, and the output pins are connected to respective counters. The pulse generators supply a pulse sequence in which the number of pulses in a group increases by one during the sequence of checking the input points and the output points, whereby each of the counters will contain only one respective number. The identificant may be provided with a monolithic semiconductor circuit, preferably on a head at its inner end, and capable of checking with respect to counterfeiting of the identificant.
