A connector for interlocking components of scaffolding or other supporting structures for building forms. The connector includes a body having an internal chamber bounded laterally by planar first and second surfaces. A lever is seated in the chamber laterally intermediate and in close fit with the planar first and second surfaces for inhibiting lateral movement of the lever. The lever is movable between a lock position and a release position. A spring is seated in the chamber laterally intermediate and in close fit with the planar first and second surfaces for inhibiting lateral movement of the spring, the spring for biasing the lever into the lock position.
