A self-adhesive security label including a movable multilayer assembly relative to a multilayer attachment assembly on an object during the application of a detachment force, the movable multilayer assembly including a transparent or translucent front material element and a printing layer located on at least part of the lower face of the front material element, the multilayer attachment assembly including an adhesive layer carried by a support from which it is removable, including: - a sectioning layer interposed between the front material element and the printing layer, in a localized manner and in a superimposed position relative to a portion of the printing layer, the sectioning layer having, relative to the front material element, a retaining force which is smaller than the detachment force of the movable multilayer assembly so that the sectioning layer and the printing layer located in the superimposed position can be separated from the movable multilayer assembly upon the application of the detachment force while the lower face of the front material element has a retaining force which, outside of this sectioning layer, is greater than the detachment force, - at least a first separation layer covering the adhesive layer, this separation layer being designed such that the retaining force between the movable multilayer assembly and said separation layer is smaller than the detachment force of the movable multilayer assembly so that the first separation layer remains secured to the multilayer attachment assembly, this retaining force being greater than the retaining force of the sectioning layer so that, upon the application of such a detachment force, the portion of the printing layer placed in the superimposed position of the sectioning layer remains secured to the multilayer attachment assembly, - the label comprising a second separation layer covering at least the printing layer, in contact with the first separation layer by being interposed between the printing layer and the first separation layer, the second separation layer being designed such that the retaining force between the two separation layers (14, 17) is smaller than the detachment force of the movable multilayer assembly and such that the second separation layer has a retaining force with the printing layer which is greater than the detachment force so that the second separation layer remains secured to the movable multilayer assembly, except for a portion placed in the superimposed position of the sectioning layer which remains secured to the multilayer attachment assembly, while the first separation layer remains secured to the multilayer attachment assembly. - a sectioning layer interposed between the front material element and the printing layer, in a localized manner and in a superimposed position relative to a portion of the printing layer, the sectioning layer having, relative to the front material element, a retaining force which is smaller than the detachment force of the movable multilayer assembly so that the sectioning layer and the printing layer located in the superimposed position can be separated from the movable multilayer assembly upon the application of the detachment force while the lower face of the front material element has a retaining force which, outside of this sectioning layer, is greater than the detachment force, - at least a first separation layer covering the adhesive layer, this separation layer being designed such that the retaining force between the movable multilayer assembly and said separation layer is smaller than the detachment force of the movable multilayer assembly so that the first separation layer remains secured to the multilayer attachment assembly, this retaining force being greater than the retaining force of the sectioning layer so that, upon the application of such a detachment force, the portion of the printing layer placed in the superimposed position of the sectioning layer remains secured to the multilayer attachment assembly, - the label comprising a second separation layer covering at least the printing layer, in contact with the first separation layer by being interposed between the printing layer and the first separation layer, the second separation layer being designed such that the retaining force between the two separation layers (14, 17) is smaller than the detachment force of the movable multilayer assembly and such that the second separation layer has a retaining force with the printing layer which is greater than the detachment force so that the second separation layer remains secured to the movable multilayer assembly, except for a portion placed in the superimposed position of the sectioning layer which remains secured to the multilayer attachment assembly, while the first separation layer remains secured to the multilayer attachment assembly.
