ABSTRACT:
An anti-shoplifting seal is constituted by a rigid body provided with a flexible and/or elastic cord, the cord being provided at the end thereof with a spike. The spike after going through an opening formed in the product to be marked is inserted in a non-removable manner within the body. The seal comprises two half-bearings placed one in front of the other and joined one to the other in a manner to form an internal cavity within which there is placed a plate of a ferromagnetic material or any other material sensitive to apparatuses marking magnetic fields, radio frequency signals and other similar sources well known at the present state of technology.
