There are essentially three types of connectors that you can use to link shapes in PowerPoint 2013 — also you can add any of these three connectors (Straight, Elbow, or Curved) as per your requirements.

You need not delete the existing connector and draw another one because PowerPoint 2013 allows you to change from one connector type to another fairly easily.
