A wedging device locatable between two components and consisting of a plurality of parts connected together such that the device remains as a single cohesive assembly during all phases of operation. The wedging device comprises a spool having two inclined surfaces and a pair of wedges arranged such that each wedge is able to be moved up one of the inclined surfaces, respectively. The device also comprises a rotatable threaded member which extends through an aperture formed in the spool and is received by the wedges. Rotation of the threaded member when the device is located between the two components causes the wedges to move toward each other up the respective inclined surfaces of the spool and be pressed against one of the components to thereby force the spool against the other said component.

[ We claim:] [1.] A wedging device adapted to secure together first and second interengaging components to prevent relative motion in a first direction, the components having respective walls defining:(i) aperture means which cooperate with one another for accommodating the wedging device; and(ii) respective abutment surfaces extending substantially at right angles to the first direction for engaging in wedging engagement with the wedging device,the wedging device comprising parts which are interconnected to form a single cohesive assembly prior to, during and after installation with the two components, the parts of the wedging device including:(a) a spool having an axis which in use is substantially at right angles to the first direction;(b) an enclosed aperture through a central portion of the spool and extending substantially in the axial direction of the spool between first and second openings to the spool;(c) the central portion having first and second ramps on the spool and providing respective inclined surfaces inclined to the axial direction and extending away from the axis in a direction generally away from the respective ends of the spool;(d) a rotatable threaded member extending through the enclosed aperture and having means to retain the threaded member captive relative to the spool;(e) first and second wedge elements mounted on the threaded member extending through first and second enclosed apertures respectively in said first and second wedge elements whereby the parts farm a single cohesive assembly, the wedge elements each having a ramp surface for engaging a corresponding one of said inclined surfaces and having an abutment surface extending substantially parallel to the axis to the spool for abutment with a corresponding abutment surface of the second component;(f) spool abutment surfaces on the side of the spool opposite to the ramps for engaging the first component and extending substantially parallel to the spool axis, the spool abutment surfaces including abutment surface. portions extending towards the axial end portions of the spool relative to the central portion; and(g) the wedge elements being configured and positioned to contact the respective ramps and to move therealong upon rotation of the threaded member, rotation of the threaded member in a first rotational direction urging the wedge elements into wedging engagement between their respective inclined surfaces and the ramps and a surface of the second component, and by reaction urging the spool abutment surfaces against the first component and rotation of the threaded member in a second rotational direction opposite to the first rotational direction permitting relief of the wedge elements from wedging engagement between their respective inclined surfaces and the ramps and a surface of the second component.
