Abstract
The fastening device for interconnecting two flat sheets of metal includes a generally rectangular hole in one of the sheets and a generally H-shaped hole in the other. The H-shaped hole includes a pair of inwardly-facing, tapered portions which are adapted to be bent into the rectangular hole of the other member. The dimensions of the tabs are such that when bent inwardly into the rectangular hole, the edges of the tabs are forced against the edges of the rectangular hole so as to cause the two members to be rigidly and securely interconnected without the necessity of the tabs being bent backwardly behind the rectangular opening in the other member.

- the tips of said tabs on said second member being movable into the rectangular holes of said first member,
- the edges of said tabs being farther apart at their base than the width of the end edges of the rectangular hole.
