Abstract
Disclosed is a fastening device and a method of removably attaching an object to a surface of a material, the fastening device including a base, rotatable around an axis of rotation; a support frame mechanically supporting the base allowing the base to rotate with respect to the support frame, the axis of rotation of the base being transverse to a reference plane of the support frame; an open-ring shaped piercing member including secured and piercing ends, secured end attached to the base, and the piercing member configured so the piercing end follows a first curved trajectory when the base is rotated; and a first abutment, on the support frame and configured to cause the piercing end of the piercing member to follow a second curved trajectory; so the plane of the second trajectory is offset by a deviation angle from the plane of the first trajectory.
