ABSTRACT:
A bracket for a wall form tightens ties used to secure the wall forms together. The bracket has a cam assembly with an inner member and an outer member axially aligned with each other. The inner and outer members have tapered abutting wedge surfaces. The outer member has a lug for receiving an end of the tie. A key may be inserted into one of the members to rotate it. Rotating one of themembers relative to the other causes the lug to move outward to tighten the tie, or to move inward to release the bracket from the tie.
