The sleeve 13 may be clamped between a shoulder 12 and a washer 15 under the head of a bolt 14 screwed into a tension sleeve 9 screwed on to the projection 8. The sections 1, 2 may be centred by teeth 7. There may be two compression sleeves one inside the other and separated by a tension sleeve, the sleeves having clearances between them smaller than that between the outer sleeve 13 and the bore 10. |
