Abstract
The specification discloses a structural connector for pivotally connecting two support members to form a folding truss. The support members can be pivoted with respect to the connector between collapsed and extended positions. The connector includes a generally planar body, a locator tab extending from the body and secured between the support members when in their extended position to orient the connector with respect to the connector, and spring clips extending from the body to lock the support members in their extended position. In an alternative embodiment, the connector includes two of the locator tabs to maintain the support members in spaced relation so that a ridge member can be positioned therebetween.
