Abstract
Plastic cross ties constructed of a plastic pipe with two separate connectors attached to both ends act as a unit to position opposing masonry shells as part of a stay-in-place concrete form system. A three part cross tie assembly constructed of a pipe and concrete from connectors are snapped together with zip rods eliminating the need for screwing, nailing or gluing.

In masonry and concrete wall construction, a plastic tie system comprising:
- ties for interconnecting and immobilizing spaced apart form walls constructed of masonry unit shells, said ties each comprising a plastic tube, a length of the plastic tube cut to match a width of a space between spaced apart form walls and shaped to accept protrusion of opposing aligned plastic connectors to be permanently connected by interlocking said plastic connectors with protrusions through an open center in the plastic tube;
- said protrusion extending through the open center of the plastic tube and having elongated arm extending down having external surface adjacent to an elongated arm extending down from a matching protrusion positioned from an opposite direction;
- said elongated arm having a plurality of ratchet teeth lining the external adjacent surface of the elongated arm;
- said ratchet teeth sloped to interlock with a plurality of ratchet teeth lining an elongated arm of a matching protrusion positioned from an opposite direction.
