Abstract

Abstract In a collapsible kite structure, a snap lock connecting assembly comprising at least two suitably rigid sticks or struts and at least one detachable bracing stick or strut, in combination with a snap lock connecting unit. The snap lock includes a fastening body portion attached to a stiffening stick, such as a wing stick of said kite, and a resilient, flexible, hollow retainer body portion configured to securely receive and resiliently hold an end part of a bracing strut. The retainer body portion of the snap lock has a longitudinal slot through the side thereof for forced passage therethrough of an end part of the bracing stick whereby the end of the bracing strut may be detachably retained in a secure position within said hollow retainer body. In a preferred embodiment the retainer body portion of the snap lock has a bead or other interengaging structure to enhance the secure retention of the end of the detachable bracing stick within the retainer body.
