6. An apparatus comprising a releasable locking mechanism for holding a line reliably connected to a downhole tool in a wellbore for providing communication with and/or power to the downhole tool, the releasable locking mechanism comprising:
a movable holding device that can be in a locked state holding the line reliably connected to the downhole tool or in a released state allowing release of the line from the downhole tool so that the line can be pulled out of the downhole tool together with the movable holding device; and
a movable locking device that can be in a locking state wherein a blocking member of the movable locking device engages the movable locking device with the movable holding device to restrict movement of the movable holding device, thereby locking the movable holding device in the locked state, or that can be in a releasing state where the blocking member no longer engages the movable locking device with the movable holding device, for releasing the movable holding device to the released state, wherein the apparatus comprises a tube forming a flow path for a fluid and wherein the movable locking device further comprises sleeve arranged in the tube and adapted for receiving an object for blocking the flow path and for building a fluid pressure in the tube, wherein the sleeve is movable by application of the fluid pressure in the tube, and wherein the sleeve, when moved, operates the movable locking device from the locking state to the releasing state by freeing the blocking member from engagement between the movable locking device and the movable holding device, wherein the apparatus comprises a support device including one or more biasing means for applying a mechanical pushing force against the sleeve to keep the sleeve in position in the tube prior to building the fluid pressure in the tube.
