ABSTRACT:
The present invention relates a fastening element for the connection of two sheets or plates (herein termed sheets) arranged at a selectable angle in relation to each other along their abutting edges using two gripping jaws able to be centrally connected with each other by means of a screw, said jaws having wings of different length and forming two bearing sockets, in each of which there are rotatable cylindrical gripping rollers provided with an axial gripping groove and consisting of elastic material.
The purpose of the invention is to provide an improved form of such a fastening element remedying the defects of known devices and making it possible to set sheets at a predetermined included angle in a single manner. In this respect it should be possible for the gripping rollers to be slipped onto the sheets easily in the non-screwed tight condition and to prevent the gripping rollers from falling out during assembly. Furthermore the device should be suitable for the connection together of elements with other cross sectional forms such as tubes or tapped sleeves.
In order to achieve these or other objects of the invention of the inner side of the long wing of the gripping jaw half forming the bearing socket a single axially extending rib is formed, which is able to be engaged selectively with one of a number of locking grooves arranged at suitable distances from each other, the two gripping rollers each being connected by means of a flexible connecting lug to form a unit.
