Tool has elongate-member extending along central passage of extraction-tube. Wedge element provided at distal-end of elongate-member located at mouth of collet. Proximal-end of elongate-member accessible at proximal-end of extraction-tube. Tool has support for reacting axial extraction force applied to extraction-tube to equipment. Tool has first-actuator at proximal-end of elongate-member. Tool configured so first-actuator causes wedge element to be pulled into collet, thereby expanding collet and causing to grip inner surface of seal.
