ABSTRACT:
A clamping device for clamping on to an elongate member, e.g. for supporting a component on the member or for strengthening the member itself, comprises an annular shell for surrounding the member, the shell being formed by a plurality of generally part annular segments, each segment having generally axially extending edges provided with outwardly projecting ribs, juxtaposed ribs of adjacent segments being engaged by engagement means to hold the segments around the elongate member. The ribs are generally wedge shaped in the axial direction of the shell. The engagement members have grooves for receiving and engaging a pair of juxtaposed ribs, the grooves having an overall shape corresponding to shape of the pair of juxtaposed ribs and are slidable axially along the ribs to draw the ribs and segments together around the elongate member. The inner surface of the shell may have a shape corresponding to that of the elongate member for engagement therewith directly or through a resiliently compressible layer, the clamping force being applied to the shell by engagement of the engagement members with the ribs, or wedge members may be provided between the shell and the elongate member, relative axial movement between the wedge members and the shell producing the required clamping stress in the shell.
