摘要： A first truss may be coupled to a second truss by securing a male coupling portion of a coupling device to the first truss, and securing a female portion of the coupling device to the second truss. An extension of the male coupling portion is positioned within an opening of the female coupling portion. The extension is provided with a groove, and the female coupling portion is provided with a lever having a cam formed on it, such that the level may be rotated causing the cam to engage the groove and secure the male coupling portion to the female coupling portion, thereby securing together the first and second trusses.
