A metal cable tie formed with an elongate metallic strap and a metallic locking head. The elongate metallic strap has a first end and a second end opposite the first end. The metallic locking head is secured to the first end of the metallic strap and comprises a strap entry face, a strap exit face, and a floor and a roof near the strap exit face for receiving the second end of the strap in order to form a closed ring structure. Moreover, a longitudinal slit and a metallic roller means are deployed between the strap entry face and the strap exit face of the metallic locking head in order to lockingly engage the metallic strap. A retention means extends from the roof of the metallic locking head to the strap exit face in order to captively hold the metallic roller means. When the strap is lockingly engaged, the metallic roller means captively held in the metallic locking head can move between the retention means near the strap exit face and a fixed position near the strap entry face, wherein the fixed position is the locking position of the roller means formed by a dent in geometric shape located on the first end of the metallic strap.
