<p>The connecting pin has longitudinal sections (2, 3) of differing diameter, to engage with opposite sections of differing dimensions. The pin (1) has an upper end section (2) with a smaller diameter (D1) and a lower base section (3) with a larger diameter (D2). The upper end is longer than the base section. It is especially more than one and a half times longer, and preferably more than twice longer. The connector is a connection socket with larger and smaller diameters as before. The differing diameters are 4 mm and 4.7 mm.</p> |
