•Sixteen monotonic push out tests on perforated connectors were performed.•Geometries include the previously proposed Perfobond and T-Perfobond connector.•Two new connector geometries are proposed: I-Perfobond and 2T-Perfobond.•The resistance, slip capacity, failure modes and stress distribution are...
