Abstract
A locking device for preventing the rotation and/or the axial movement of a pin includes a coil spring wound around at least a portion of the pin and having one end rigidly connected to a support structure. In its undeformed condition, the spring has an internal diameter smaller than the diameter of the pin, whereby in its resting condition the spring is tightened around the pin to prevent a rotation thereof at least in a direction or an axial movement in any direction. The device includes shape memory means for causing the unwinding of the turns of the spring for the purpose of temporarily releasing the pin.
