1. A multi-prong connector used in making a composite wall structure which includes first and second structural layers comprising a hardenable material and an insulating layer disposed between the first and second structural layers, wherein the connector comprises an insulating material and includes:

  • (a) a gripping segment having a bridging structure;

    (b) a plurality of elongate prongs attached together by and extending from the bridging structure, each prong having a penetrating segment distal to the bridging structure and a mesial segment disposed between the penetrating segment and the gripping segment;

    (c) a penetrating tip disposed on an end of at least one of the prongs and having a reduced cross-section width relative to the rest of the prong;

    (d) first anchoring means disposed within the penetrating segment of at least one of the prongs for anchoring the connector within the first structural layer when substantially hardened; and

    (e) second anchoring means within the gripping segment for anchoring the connector within the second structural layer when substantially hardened.
