Cut you a piece of tight fitting fuel line and put over each end of the shaft.The spring loaded chute does keep it on but only if the chute doesn't start slipping off the chrome bar, which mine always does. Eventually it will fall off and if you're not paying close attention, you run it over. It's a bad design. The first one I chewed up came with the mower so it was the correct chute and the second one from Amazon was identical. As you suggest, I intend to wire or tape the next one on to the fitting so this doesn't happend again. Thanks for the advice..
