Abstract
Abstract A clip for pinning an assembly of sheet metal plates or the like together including a bearing face adapted to come into contact with the outer face of one of said outer plates of said assembly of sheet metal plates; at least one elongated element, adapted to pass through holes in register made in the plates of said assembly of sheet metal plates and provided with a hooking beak; and a mechanism for creating a relative displacement, of longitudinal direction, between said elongated element and said bearing face and possibly a transverse displacement of said hooking beak, so that said plates may be pressed between said bearing face and said hooking beak. The clip comprises a protecting tube made of a deformable material and surrounding said elongated element, including said hooking beak.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
160 words
A clip for pinning together sheet plates joined face by face and forming an assembly having two outer plates, said clip comprising: a bearing face adapted to come into contact with the outer face of one of said outer plates of said assembly of sheet plates; at least one elongated element, adapted to pass through holes in register made in the plates of said assembly of sheet plates and provided with a hooking beak; and a mechanism for creating a relative longitudinal displacement between said elongated element and said bearing face for pressing said plates between said bearing face and said hooking beak, which is then hooked behind the outer face of the other outer plate of said assembly of sheet plates, said clip further comprising a protecting tube made of a deformable material and surrounding said elongated element, including said hooking beak, said protecting tube being able to be introduced through said holes and then eliminated from said holes.
Claim 2
Dependent Claim
160 words
A clip for pinning together sheet plates joined face by face and forming an assembly having two outer plates, said clip comprising: a bearing face adapted to come into contact with the outer face of one of said outer plates of said assembly of sheet plates; at least one elongated element, adapted to pass through holes in register made in the plates of said assembly of sheet plates and provided with a hooking beak; and a mechanism for creating a relative longitudinal displacement between said elongated element and said bearing face for pressing said plates between said bearing face and said hooking beak, which is then hooked behind the outer face of the other outer plate of said assembly of sheet plates, said clip further comprising a protecting tube made of a deformable material and surrounding said elongated element, including said hooking beak, said protecting tube being able to be introduced through said holes and then eliminated from said holes.
