Abstract:
A reversible fastening device (50) comprising connecting means (51) connecting a first (52) and a second (53) member, said connecting means (51) comprising an elastic gripper housed inside said first member (52) coaxial with a given axis; actuating means for transporting and activating said elastic gripper, said actuating means comprising a piston coaxial with and inside said elastic gripper; and a mechanism for moving said piston and said elastic gripper, at a first reversible stage, from a withdrawn position to an extracted position projecting with respect to said first member (52) and for moving said piston, at a second stage, subsequent to said first stage, from said extracted position to an intermediate position between said extracted position and said withdrawn position, in order to deform elastically said elastic gripper so as to cause the elastic gripper to engage at least one seat on said second member.
