ABSTRACT:
An expansible rivet for securing together overlapped panels comprises a female member having a plurality of elastic legs defined by a corresponding number of axially elongate notches and a male member having a body portion having axially elongate fins slidably received in the axially elongate notches and a conical free end portion. The fins serve to permit stable coupling of the two members. The conical end portion facilitates the insertion of the male member into the female member.
