The old trick for motorcycle handgrips is to spray the bar with hairspray, then quickly slide the grip on. The spray lubes the bar so you can get the grip on, then cements it in place once it dries. Bond is strong enough to hold, but reversible....

Just wrap the stick with electrical tape think enough that you can slide the grip on with a lot of force. If you apply the right thickness of tape, it will hold on very good, and is removable anytime with some turning and pulling.
