<p>A wellbore pipe protection device (1) comprises a covering sleeve (2) and an actuating element (3). The actuating element is arranged to change the deformation state of a sleeve wall (21) of the covering sleeve in order to realize interchangeability between a locked condition and an unlocked condition of the protection device. In the locked condition, elastic material (4) is being pressed by the sleeve wall into screw thread (8) of a wellbore pipe end (7). The actuating element comprises a handgrip (9) which, relative to the covering sleeve, is manually slidable in axial direction (5) and, in the locked condition, manually rotatable about the axial direction into a rotation position in which axial slidability of the actuating element is blocked in a direction towards the unlocked condition.</p> |
