A sealing device in the form of a plug that is receivable in a threaded hole of a case includes a threaded central body, a skirt connected to the central body, and locking/unlocking means that opposes spontaneous unscrewing of the plug and is automatically activated by rotation of the plug and corresponding movement along an axis. The locking/unlocking means includes a first releasable coupling component coupled for rotation with the central body, and a second releasable coupling component facing the first coupling component at least during screwing and unscrewing. In at least in a tightened condition of the plug, the second coupling component is secured against rotation relative to the case by rotation restricting means located inside the threaded bore. In the screwed condition, an annular end face of the skirt bears against a bearing face of the second releasable coupling component to transmit tightening thrust to the case.
