ABSTRACT:
A jointing device including arms which connect two elements together. The arms are elongated and of generally rectangular cross-section. One of the elements includes flanges with lips extending along the edges of the flanges and the other of the elements forms a clip. The lips form a mouth. Each arm is grooved near one end, the grooves extending transversely across one of the elongated faces of the respective arm. Said one end of each arm is bounded by a rolling surface which intersects said one surface of each arm and merges with the opposed surface. With the rolling surfaces in engagement, the arms diverge from said one end and, in this condition, can be inserted into, and removed from, said mouth. When the outer ends of the arms are moved together from this diverging position, the arms are brought into back-to-back relationship with the opposed surfaces juxtaposed. The lips are received in the grooves while the arms are held in back-to-back relationship in the mouth. The arms are held in this relationship by the second element which straddles the arms. The lips are forced apart as the arms are brought into this relationship because the distance between the bottoms of the grooves is greater than the initial distance between the lips.
