A structural tie shear connector for use with a concrete and insulation composite panel. The panel has a first concrete wythe, a second concrete wythe, and an insulation layer interposed between the first and second concrete wythes. The connector has two sides extending in a direction substantially parallel to a longitudinal centerline of the connector and two sides extending across the longitudinal centerline of the connector. First and second pairs of angular links are connected to the sides, and a pair of legs are connected to, and extend outward from, one side of the connector. The connector is extendable through the insulation layer and into the first and second concrete wythes to hold the panel together.
