The device is for fitting lining segments in deep wells and consists of a central part (1) with a top suspension eye (3). A pivoted mechanism (11) has rests (12) which can move transversely between a disengaging and an engaging position. The lining may be lifted and others superimposed on it. The central part (1) is tubular and coaxial with the lining and the mechanism (11). A framework (4) goes around the central part coaxially.
