-13- A LOCKING CONNECTOR FOR SUSPENSION CEILING SYSTEMS ABSTRACT OF THE DISCLOSURE An end connector structure for suspension ceiling grid systems provides a connector to connector lock on each side of the web of a through runner. The lock includes a lateral tear drop shaped protrusion providing a rearwardly facing exposed edge in combination with a lateral strap on an associated identical connector which also provides a rearwardly facing exposed edge. When tensile stresses are applied between the two connectors, the connector to connector lock is subjected to forces causing the associated rearwardly facing edges to engage and resist connector separation. The protrusion joins the adjacent portion of the connector material with bends having relatively large radius of curvature to reduce the weakening of the structure of the protrusion resulting from notch sensitivity. These large radius of curvatures result in substantially improved ultimate strength in the connector to connector lock when compared with protrusions formed with relatively sharp bends.
