An attachment arrangement 16A has two collet arrangements 20A, 22A. A main body 52 has a passage 54 containing taper inserts 57, 57A. Collar parts 42A are housed within the inserts 57, 57A. The collar parts 42A also abut a spacer 60 which is free to move axially within the passage 54. The length of the passage is governed by a member 68, threaded in the main body 52. As the member 68 is tightened, the collar parts 42A are squeezed between the spacer 60 and the respective tapering walls 59, 59A of the inserts 57, 57A. This presses the collar parts 42A inwardly to grip a rebar 12 which has been inserted within the body 52. <IMAGE> |
