A hose accessory includes a handle, a shaft slidably received in the handle, and a flexible conduit located within handle and shaft. The flexible conduit may be arranged to carry fluids between a first end of the hose accessory and a second end of the hose accessory. A lock is provided to secure the shaft in a fixed position relative to the handle. The lock may include a locking pin biased towards a locked position. The shaft may include first and second channels. The first channel receives at least a portion of the locking pin when the locking pin is in a locked position. The conduit extends through the second channel that isolates and separates the conduit from the locking pin.
