A connecting device for connecting segments of concrete or similar settable material, the device including a plastics connector part (1) of dumb-bell-like form and two housing parts (4) for receiving respective opposite portions (2) of the connector part. Each housing part has an internal tapered form so that, when the housing parts are set in opposed concrete segments to be connected and the connector part is inserted in the housing parts, the taper of each housing part causes the connector part to stretch thereby providing a tensile load between the opposite portions (2) of the connector part. Preferably, the taper has two angles of slope, the leading section causing the connector part to stretch and the hind section of taper causing the connector part to be trapped therein by relieving a measure of the stretch.
