Connecting apparatus for use with centre pivot irrigation equipment that includes a boom supported on ground wheels and made up of one or more pipes arranged to rotate about a water supply pipe to which the boom is connected. The apparatus is provided with a U-shaped flexible pipe assembly for connecting the boom to the water supply pipe so as to enable the boom to move radially towards and away from the water supply pipe as it rotates while remaining connected thereto. This radial movement causes the distance between the ground wheels and the water supply pipe to vary and reduces the damage caused to a crop and the land in the path of the wheels. The apparatus includes a structure that is rigidly connected to the inner end of the boom. The structure may include rails that slide over a seat mounted on the water supply pipe.
