The fastening device comprises a housing having a joint for connecting to the link, and two coaxial pins for joining it to the object, of which at least one is mounted in a manner that enables it to slide between two positions, one being retracted from the wall of the housing and the other projecting from the wall of the housing for engaging inside an opening of the object, coaxial to a second opening for accommodating the other of these pins. The fastening device also comprises an elastic device for attempting to constantly hold the sliding pin in the retracted position and an activating element associated with a cam for displacing the sliding pin into the other position. When the sliding pin is in the retracted position, the internal extremities of the pins abut against one another, their respective surfaces being adapted for providing a space at the periphery thereof capable of receiving the extremity of a position of the cam.
