A single-layered protective zipper, comprising a zipper base (1), a chain (2), and a steel tape measure (3). The chain (2) comprises a left chain (4), a right chain (5), a zipper head closing element (6), and a zipper tail closing element (7). The left chain (4) is constituted by connecting left teeth (8) to a left tape (9). The left teeth (8) are provided with left insertion-proof plates (10) and left hooks (11). The right chain (5) is constituted by connecting right teeth (12) to a right tape (13). The right teeth (12) are provided with right insertion-proof plates (14) and right hooks (15). The steel tape measure (3) is provided with a steel tape strip (16). The steel tape strip (16) is arranged between the left hooks (11) and the right hooks (15). The left insertion-proof plates (10) are arranged at corresponding positions between the left teeth (8). The right insertion-proof plates (14) are arranged at corresponding positions between the right teeth (12). When in use, the zipper is mounted on a piece of luggage or a luggage bag, the left insertion-proof plates (10) and the right insertion-proof plates (14) are utilized to block the corresponding gaps between the left teeth (8) and between the right teeth (12); at the same time, the steel tape strip (16) is utilized to block the underside of a zipper closure; hence, when a criminal is inserting a sharp tool into the chain (2), the sharp tool is blocked by the steel tape strip (16), thus making insertion difficult.
