ABSTRACT:
A connector for a channel, the latter having a web and side flanges with inwardly turned, hook-shaped lips defining a slot therebetween. The connector comprises an elongate connecting member generally U-shaped in cross-section having a pair of side walls. The member is axially inserted inside the channel with the open side of the member toward the channel slot and the side walls of the member adjacent and parallel to the side flanges of the channel. A cam is mounted in a side wall of the member for movement from a retracted to a locking position in which the cam engages a lip of the channel when the member is inside the channel to force the member toward the web of the channel for engagement therewith thereby rigidly securing the channel to the member.
