Equipment for delivering a fluid, such as herbicide, comprises a carrier in the form of a handset and a support tube 4, one end of which is removably connected to the carrier and the other end of which carries a distribution head. Within the support tube 4 a supply duct 6 conveys herbicide from the carrier to the distribution head, and electrical leads 8 provide a connection between the carrier, and the distribution head. The support tube 4 has a connector 10 which is releasably secured to the carrier by a screwthreaded sleeve 52. A spigot 18 of the connector 10 enters a bore in a valve of the carrier to provide sealed connection between the valve and the supply duct 6. First contacts 38 on the connector 10 engage second contacts 42 in the carrier to provide electrical connections. The support tube 4 can thus be coupled to the carrier 2 by a simple plug-in operation. <IMAGE> |
