<p>The device (14) has a connecting rod (16) coupled to movable elements i.e. half-shells (4, 5), at the level of its ends (18, 19), respectively. The end (19) has a plate shaped head (22) for cooperating with a locking unit (23) locking the half-shell (5) to realize a removable fixation of the connecting rod on the half-shell (5). A telescopic guiding unit (25) supports and guides the connecting rod during movement of the half-shells. The guiding unit has tubular elements (28, 26) adapted to be attached to the locking unit and the connecting rod, respectively.</p> |
