<p>A pin to connect together two elements, such as a box and its cover, or other couplings, and its relevant seat suitable to house the pin. This pin is characterized by having on the stem at least a couple of protruding tabs (4, 5, 6, 7) able to grip a cylindrical wall of the seat when the pin is rotated of an angle of 90<o>. The seat presents, for this purpose, thin walls (12, 13) elastically deformable to facilitate the gripping action of the tabs and at the same time capable of exerting a pressure.</p> |
