Abstract

In a positive coupling structure for interconnecting a first element having a T-shaped projection with a neck and a head portion which extends from the neck portion in opposite directions and a second element which has a cut-out shaped corresponding to the T-shaped projection of the first element for snugly receiving the T-shaped projection, the opposite ends of the head portion are widened to form recesses in which the adjacent areas of the second element are firmly engaged.
