A tool for locking and releasing a plug in a hydrocarbon well includes a sleeve having at least one pocket for receiving the plug's pin element, and at least one locking element which can be moved between a release position in which the pocket is open, and a locking position in which the pocket is closed. When locking the tool to the plug, the tool is moved in the hydrocarbon well to facilitate positioning of the pin element in abutment with the locking element, further movement bringing the locking element into an open position for receiving the pin element in the pocket, and the locking element is brought into a locking position such that the plug's pin element is locked in the pocket. When releasing the tool from the plug, fluid means are used for movement of the locking element into a release position. |
