Abstract: A unilaterally bondable, transparent, substantially two-dimensional element (2D element) is presented which has a support and an adhesive, and which is used as a shatterproofing device for brittle 2D bodies. The surface of the support is protected from damage by means of a temporary covering means. The temporary covering means is designed such that it is residue-lessly detachably joined to the support and hence ensures optimal transparency of the 2D element following detachment of the temporary covering means.
