Anti-theft device

An anti-theft tag, comprising:

• a fixed component and a moving component, with the moving component moved to frictionally clamp and secure the anti-theft tag onto an article without puncturing the article;
• the fixed component is comprised of:
• a body, a shoulder, and a cantilever arm that define a gap with substantially “U” shaped profile for securing the article therein;
• with the body including a through-hole for insertion of the moving component;
• the moving component includes a movable subcomponent that is moved to extend away from the moving component to provide a tighter grip of the moving component with the article;
• the moving component is comprised of:
• a grip portion that contacts the article with which the anti-theft tag is coupled for frictionally clamping and securing the article;
• and
• a piston that has a translational movement that enables the moving component to move through the through-hole and via a set of complementary oriented beveled serrations interlock with a lock mechanism at a desired position;
• the piston further includes the moving subcomponent that pivotally extends by a rotating mechanism to further tighten the grip portion contact with the article.

Anti-theft tag, comprising:

• a fixed component and a moving component, with the moving component moved to frictionally clamp and secure the anti-theft tag onto an article without puncturing the article;
• the moving component having a movable subcomponent that is moved to extend
• away from the moving component to provide a tighter grip of the moving component with the article;
• guiding notches that enable the moving component to move along a reciprocating path within a through-hole of a body of the fixed component;
• and
• a set of lateral biasing mechanisms that bias and support the moving component at a default position, and
• an interlocking mechanism that includes:
• a biasing mechanism that biases a first side of a clutch with serrations against serrations of the moving component, with first side of the clutch and the moving
• component having complementary oriented beveled serrations.
