Abstract: A locking and holding system for jewelry insertable into a pierced body part is disclosed. The locking and holding system includes a shaft having at least one throat or opening, a pivot pin, and a locking bar in rotational engagement with the pivot pin. The locking bar may be rotated into a insertion orientation such that the locking bar is engaged in an interfering fit with the throat to retain the locking bar. After insertion of the shaft through the pierced opening, the locking bar may be rotated into a locking orientation to retain the item of jewelry to the person's body.
