Abstract (en)
[origin: US4530390A] A metallic link for a blind slat having a flange comprises a head portion with a suspension aperture for receiving a supporting loop, and with stop shoulders applying against the outer wall of the flange. Integral with the head parts is a clamping ring portion having at least one cutting edge on its front end. Initially, the clamping ring is straight and longer than the width of the cavity formed by the flange. Then, the ring portion is driven through the outer wall of the flange, up to the stop shoulders of the head. As the cutting edge 5 pierces the inner wall of the flange, the clamping ring undergoes a permanent deformation and buckles so that its sides are bent out and the ring becomes firmly clamped in the flange. Except for a ram for driving the link in, no other tool is needed.
