I can think of a few options. It all depends on how clean you want it to look.
1) Drill a hole through the pump shaft and then glue/epoxy the handle back in place. After the glue/epoxy has set (handling time) take a zip-tie or two and run them through the hole you drilled and around the handle. Cinch them tight and that should be strong enough.
2) I'm not sure if the pump shaft is hollow or not...if it is hollow insert a rod that fits...if it's not hollow drill a hole and insert a rod. Make sure the rod extends from the pump tube to the pump handle then glue/epoxy it back together.
3) Another option is to make a whole new pump handle. Dremel/Sand/Cut/Pry the plastic opening where the pump tube goes through so that 1/2" CPVC can fit through it. Cut the tip of the old pump tube (including the head with o-ring, holes, etc.) and glue that to the CPVC. To make a handle use a Tee coupler (if you want it to be a loop you'll need four elbow couplers as well).
There are more options. One thing to consider is the contact surface between the pump handle and pump tube? Can the tube fit at all inside the handle or did it break exactly where the two meet? If the pump can fit a little bit inside the handle, just epoxying it should be enough (and zip-ties are a nice reinforcement if you're worried about it.
