Abstract
A telescopic connection structure for connecting two sections of pipe or hose comprises an extension pipe and a connection member 30. The extension pipe includes an outer tube 22 and an inner tube 21 slidably mounted therein. The connection member 30 is made up of first and second connectors 31,32 which are connected together by complementary screw threads 33,34. The first connector 31 includes elastic retaining pieces 37 arranged at intervals around its perimeter. The outer tube 22 is fastened at one end to a lower portion of the first connector 31 and is connectable at its other end to a first pipe, such as a handle (10, Fig 1), and the slidable inner tube 21 is connectable at its exposed end to a second pipe, such as a nozzle (40, Fig 1). When the first and second connectors 31,32 are connected, the elastic retaining pieces 37 are constricted so that they engage the wall of the inner pipe 21 thus locking the extension pipe at the required length and when the connectors 31,32 are released the length of the extension pipe can be altered. Also disclosed are spray attachments for a hose or pipe which include other connection arrangements.
