A sprinkler includes a handle, a nozzle, and a connection structure for connecting the nozzle to the handle. The connection structure has an extension pipe and a connection member. The extension pipe is formed of an outer tube fastened at a bottom end to the handle, and an inner tube fastened at a top end to the nozzle. The connection member is formed of a first connector and a second connector. The first connector is engaged with a top end of the outer tube and is engaged with the second connector. The inner tube is slidably fitted at a bottom end into the top end of the outer tube through the first connector such that the inner tube is intimately embraced by the first connector.
