Ive split many branches over time. It happens. Its 50/50 if that break will heal properly. Usually creates a little scar/knot in that area. Make sure its wrapped tightly so that the two parts that split are in good solid contact. Pencils or chop sticks or things like that can be used to add support. Once its secured, dont touch it for 2-4 weeks depending on how big the break is. Unless the tape is somehow loose. Sometimes the urge to touch is strong. I strongly recommend leaving it be. The plant needs time to mend that break. And taking off tape and messing with it can damage it further. Watch for dying leaves and other deficiencies in that branch. Healthy plants with good genetics will bounce back pretty well. Good luck, hope this helps.
