The invention claimed is: 1. A pivotable suspension element comprising a support member having a part-spherical bearing surface, clamp means and a body portion, said body portion comprising an integral formation of: a slot to receive a part of a component to which the pivotable suspension element may be secured; a locator formation for the clamp means whereby, in use, the clamp means may be operated to clamp a flange in the slot; a part-spherical seat, and a through-passage extending through the body from said part-spherical seat, wherein the curvature of said part-spherical seat of the body portion corresponds substantially with that of the bearing surface of the support member and said part-spherical seat of the body portion is subject to the weight of a supported load carried by the support member, and wherein the cross-sectional size of the through-passage increases in a direction away from said part-spherical seat. 2. A pivotable suspension element according to claim 1, wherein the support member is provided with a through-passage in the form of a through-bore in communication with the part-spherical bearing surface for location of an elongate suspension member. 3. A pivotable suspension element according to claim 2, wherein said through-bore is cylindrical. 4. A pivotable suspension element according to claim 2, wherein said through-bore is of a cross-section which decreases from a maximum at the part-spherical surface to a minimum at a remote surface of the support member. 5. A pivotable suspension element according to claim 1, wherein the part-spherical seat of the body portion is concave and the part-spherical bearing surface of the support member is convex. 6. A pivotable suspension element according to claim 1, wherein the body portion comprises two locator formations positioned respectively in two sections of the body portion which define said slot. 7. A pivotable suspension element according to claim 1, wherein each locator formation for the clamp means comprises a screw-threaded passage formed in the body portion and extending into communication with the slot. 8. A pivotable suspension element according to claim 7, wherein the clamp means comprises a screw-threaded bolt provided in a said screw-threaded aperture and a lock nut whereby the bolt may be locked in a position at which the flange of a support member is clamped in the slot and held firmly in that configuration. 9. A pivotable suspension element according to claim 1, wherein each locator formation extends in a direction parallel with the length direction of said through passage of the body portion. 10. A pivotable suspension element according to claim 1, wherein the support member is formed integrally with an elongate suspension member. 11. A pivotable suspension element according to claim 1, wherein as considered in the direction of the length of the through-passage of the body portion, said body portion defines a pair of end faces and the part-spherical seat of the body portion extends in said length direction to a position aligned with one of said end faces. 12. A pivotable suspension element according to claim 1, wherein as considered in the direction of the length of the through-passage of the body portion, said body portion defines a pair of end faces and the part-spherical seat of the body portion lies inset from said end faces. 13. A pivotable suspension element according to claim 12, wherein the major diameter of the part-spherical seat lies substantially mid-way between said end faces. 14. A pivotable suspension element according to claim 12, wherein the material of the body portion is shaped to define a recess whereby a space adjacent a surface of the support member may be accessed in a sideways direction between said end faces. 15. A pivotable suspension element according to claim 1, wherein the body portion is provided with a pair of said substantially part-spherical bearing seats disposed in a back to back manner. 16. A pivotable suspension assembly comprising a pivotable suspension element according to claim 1 and an elongate suspension member which extends through said through-bore and has a screw-threaded end region. 17. The assembly of claim 16, wherein a lock nut arrangement is provided at said screw-threaded end whereby the effective suspension length of the suspension member may be adjusted in situ and retained securely in that adjusted position. 18. A pivotable suspension assembly comprising a pivotable suspension element according to claim 4 and an elongate suspension member which extends through said through-bore, wherein the dimension of the through-bore at said remote surface corresponds substantially with the cross-sectional dimension of the elongate suspension member. 19. A pivotable suspension element comprising a support member having a part-spherical bearing surface, clamp means and a body portion, said body portion comprising an integral formation of: a slot to receive a part of a component to which the pivotable suspension element may be secured; a locator formation for the clamp means whereby, in use, the clamp means may be operated to clamp a flange in the slot; a pair of end faces; a through-passage extending through the body from one of said end faces to the other; and a part-spherical seat which lies inset from said end faces and through which said through-passage extends, wherein the curvature of said part-spherical seat of the body portion corresponds substantially with that of the bearing surface of the support member and wherein the cross-sectional size of the through-passage increases in a direction away from said part-spherical seat. 20. A pivotable suspension element according to claim 19, wherein the support member, when in sit with the bearing surface thereof in contact with said part-spherical seat, lies substantially wholly between said end faces. 21. A pivotable suspension element comprising a support member having a part-spherical bearing surface, clamp means and a body portion, said body portion comprising an integral formation of: a slot defined by the space between two sections of the body portion to receive a part of a component to which the pivotable suspension element may be secured; two locator formations for the clamp means, said two locator formations being positioned respectively in said two sections of the body portion whereby, in use, the clamp means may be associated with either of the two locator formations and operated to clamp a flange in the slot; a part-spherical seat; and a through-passage extending through the body from said part-spherical seat, wherein the curvature of said part-spherical seat of the body portion corresponds substantially with that of the bearing surface of the support member and wherein the cross-sectional size of the through-passage increases in a direction away from said part-spherical seat. 22. A pivotable suspension element according to claim 21, wherein the body portion comprises a pair of end faces at axial extremities thereof as considered in the direction of the length of the through-passage and said support member, when in sit with the bearing surface thereof in contact with said part-spherical seat, lies substantially wholly between said end faces.
