Self-locking plug

A self-locking plug, comprising:

• a body component;
• a flexible beam finger component disposed about the body component and including a plurality of axially-oriented flexible beam fingers;
• a tab sleeve component disposed within the flexible beam finger component and including one or more downward extending tabs;
• an annular detent ring component including a plurality of circumferentially-arranged detents separated by ridges in radial alignment with the plurality of flexible beam fingers;
• and
• a wave spring disposed between the tab sleeve component and the annular detent ring component for providing a biasing force to urge the tab sleeve component in a direction of a central, longitudinal axis, A, of the self-locking plug,
• wherein the flexible beam finger component moves relative to the annular detent ring component when the body component is rotated about the central, longitudinal axis, A, of the self-locking plug, thereby causing the plurality of flexible beam fingers to travel across the plurality of detents and cause elastic deformation of the flexible beam fingers.
