An interlock connector (10) for interlocking stackable building blocks (26). The blocks are provided with apertures (32), such as grooves, on their top a nd bottom surfaces. The connector comprises a main body which includes two separate and vertically superimposed body portions and is interposed between two stacked blocks with each body portion disposed in a respective groove (32). One body portion is pivotable with respect to another, with a vertical pivot axis that is offset from the central vertical axis of the main body, s o as to be pivotable to positions where the stacked blocks are offset. In another embodiment, the interlock connector comprises a single piece main bo dy having an aperture to receive a projection protruding from the surface of on e of the stacked blocks while being disposed in the groove of the other block, with the connector being pivotable about the projection to positions where t he stacked blocks are offset. Other embodiments include connectors with offset upper and lower body portions to interlock blocks having symmetrical grooves , wherein certain of the embodiments allow a block to be pivoted about a body portion.
