Abstract
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.
