A through-insulation connector assembly for use in the construction of insulated concrete sandwich wall. The connector assembly includes a spool-shaped connector body comprised of two, interconnecting pieces and a tie that engages the connector body. The two pieces of the connector body are installed at the place of manufacture in a sheet of foam insulation board that will be used as the insulation layer in the construction of an insulated concrete sandwich wall.

1. A connector assembly for use in forming insulated concrete sandwich walls having an insulation layer sandwiched between two concrete layers, comprising:(a) a first connector piece positioned on one side of the insulation layer; (b) a second connector piece positioned in axial alignment with the first connector piece on the opposite side of the insulation layer; (c) cooperative engagement elements on the two connector pieces that interlock the two connector pieced together upon movement of the two connector pieces into contact engagement with each other; and (d) a tie inserted into the interlocked connector pieces and having end portions which extend to either side of the insulation layer. 2. A connector assembly as defined in claim 1, wherein the tie is oriented after its insertion in the interlocked connector pieces to prevent its retraction or further advancement.3. A connector assembly as defined in claim 2, wherein in the tie is pivoted to prevent its retraction or further advancement.4. A connector assembly as defined in claim 2, wherein hand graspable projections are provided on the tie to facilitate its orientation.5. A connector assembly as defined in claim 1, further comprising retaining elements on either the first or second connector piece for retaining the tie in position inside the interlocked connector pieces after its insertion.6. A connector as defined in claim 5, wherein the tie is oriented after its insertion in the interlocked connector pieces to prevent its retraction or further advancement and the orientation of the tie engages the retaining elements.7. A connector as defined in claim 1, wherein the cooperative engagement elements comprise a detent and latch, one of which is on the first connector piece and the other of which is on the second connector piece.8. A connector as defined in claim 7, wherein the detent comprises a fixed ear and the latch comprises a flexible clip that passes over the fixed ear as the pieces are moved toward the interlocked position and which engages the ear in the interlocked position to prevent disengagement of the two interlocked pieces.9. A connector as defined in claim 1, wherein the cooperative engagement elements comprise a detent and latch associated with each connector piece wherein the detent of the first piece is engaged by the latch of the first piece upon movement of the two pieces toward the interlocked position to prevent disengagement of the two interlocked pieces.10. A connector assembly for use in forming insulated concrete sandwich walls having an insulation layer sandwiched between two concrete layers, comprising:(a) a first connector piece positioned on one side of the insulation layer; (b) a second connector piece positioned in axial alignment with the first connector piece on the opposite side of the insulation layer, (c) cooperative surfaces on the two connector pieces that abut each other upon movement of the two connector pieces into contact with each other; (d) means securing the first and second connector pieces to each other at the cooperative surfaces to interlock the pieces together; and (e) a tie inserted into the interlocked connector pieces and having end portions which extend to either side of the insulation layer. 11. A connector assembly as defined in claim 10, wherein the securing means comprises welding.12. A connector assembly as defined in claim 10, wherein the securing means comprises an adhesive.13. A connector assembly for use in forming insulated concrete sandwich walls having an insulation layer sandwiched between two concrete layers, comprising:(a) a first connector piece positioned on one side of the insulation layer; (b) a second connector piece positioned in axial alignment with the first connector piece on the opposite side of the insulation layer; (c) a docking member positioned in axial alignment between the first and second connector pieces; (d) cooperative engagement elements on the two connector pieces and the docking member that interlock the two connector pieces to the docking upon movement of the two connector pieces into contact engagement with the docking member; and (e) a tie inserted into the interlocked docking member and connector pieces and having end portions which extend to either side of the insulation layer. 14. A method of constructing an insulated concrete sandwich wall having an insulation layer sandwiched between two concrete layers, comprising the steps of:(a) positioning a first connector piece on one side of the insulation layer; (b) positioning a second connector piece on the opposite side of the insulation layer in axial alignment with the first connector piece; (c) providing cooperative engagement elements of the two connector pieces; (d) moving the two connector pieces into contact engagement whereupon the cooperative engagement elements interlock the two connector pieces together; and (e) inserting a tie into the interlocked connector pieces-to a depth where end portions extend to either side of the insulation layer. 15. A method as defined in claim 14, further comprising the step of orienting the tie after its insertion into the interlocked connector elements to prevent its retraction of further advancement.
