A transversely ribbed plastics strip 26 extends around the slotted portion of a tube 12 and passes through a guide 30 which is shaped to fit around part of the tube. A threaded nut 32 is screwable onto the free ends of the ribbed strip 26 which are separated by a spacer forming part of the guide. By rotating the nut 32, the ends of the strip 26 are drawn through the guide 30 and the strip deforms the upstanding portions 24 inwardly. In use, the handle of a tool is placed in the slotted end of the tube 12 and the nut 32 is rotated to deform the upstanding 12 portions 24 which grip the handle of the tool. Thus, the effective length of the tool is increased. The lower portion of the tube is provided with towelling 14 which affords a good grip. <IMAGE> |
