A device configured to protect a female end of a component of a threaded tubular connection for drilling and working a hydrocarbon well, including an internal threading, an annular end, and internal surfaces respectively upstream and downstream of the internal threading and respectively having first and second selected orientations. The device includes a body including an external threading to cooperate with the internal threading and first and second flexible annular sealing elements respectively upstream and downstream of the external threading to provide first and second seals respectively at the internal and end annular surfaces. The first and second sealing elements have selected third and fourth orientations at least one of which differs by at least 10&#xb0; from the corresponding second or first orientation before screwing the device onto the female end, and are deformable by axial bending to acquire, by surface contact with the internal annular surface and the annular end surface, an energy at least partially opposing any unintentional unscrewing when the female end is screwed onto the body in a final position.

A protective device for a male end of a component of a threaded tubular connection for drilling and working hydrocarbon wells is externally provided with at least one threading and includes a free terminal portion. The device includes i) a protector body produced in the form of a first sleeve and arranged to protect at least a portion of the external threading and the free terminal portion, ii) a sealing element for positioning in contact firstly with the component, at least at a portion located downstream of the external threading of the male end, and secondly with the protector body to provide a first seal downstream of the external threading, and iii) a fixing mechanism displacing the sealing element and/or protector body radially towards the component, defining open and closed positions of the device in which the sealing element and/or the protector body are respectively not in contact and in tight contact with the component. Further, the first seal is obtained in the closed position of the device.
