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.

An assembly for axial fixation of at least one element having an opening formed therein to an article. The assembly includes an anchoring protrusion attached to the article, which includes a distal end and a neck portion, and at least one locking component having a bore disposed therein, the locking component having at least a portion which is at least one of flexible and elastic. The anchoring protrusion extends through the opening in the element and through the bore of the locking component. An overlap region between the opening of the element and the bore of the locking component, is substantially equal to the diameter of the neck portion, such that the element and the at least a portion of the locking component form a locking unit.
