<p>The invention relates to a connecting device comprising three elements, namely: a core (1; 50) which is housed in an inner part (3; 70) and an outer part (2; 60). The core (1; 50) consists of a head (5; 53) comprising a truncated-cone-shaped part (5A; 54) and a rod (4; 51) having, for example, one of the two sides of a collar connected thereto, the other side being connected to the outer part (2; 60). According to the invention, the inner part is snap engaged in the outer part (2; 60) and is simultaneously detached from the core. The above-mentioned head is shaped such that, in the closed configuration, the head inhibits the engagement means (10; 72) such that the device locks when the rod (4; 51) is pulled.</p> |
