The invention concerns a device for providing a friction joint. It comprises an inner (1,11) and an outer (2,9) element, the inner element having a tapered outer surface co-operating with a complementary tapered inner surface in a bore in the outer element. Means (6,7,8,12) are provided for displacing the elements axially parallel to the taper axes. One element preferably consists of a slitted clamping sleeve, and for diminishing the friction in the tapered contact and simplifying manufacturing of the parts of the device, one of the tapered surfaces is provided with a friction reducing material and one of the tapered surfaces has a groove (3,4,5,13,14,15,16) extending around the circumference. |
