Claim 1
Independent Claim
192 words
Clamping binder for two angularly meeting moldings, comprising: two levers joined pivotingly to one another at a pivot axis, each lever having a free end, two fastening pins respectively connected to the free ends, and projecting laterally from said ends and approximately parallel to the pivot axis and insertable respectively into the moldings to be joined, each lever having a section which is substantially straight in the area of the end bearing the respective fastening pin, and also has an adjoining curved or angled section, one lever being pivotingly joined at its curved or angled section to the other lever in an area on the other lever situated between the ends of the other lever, and tightening means adjustably fastened to one of said two levers and bearing against the other lever, said tightening means forming thrust-tightening means arranged between said curved or angled section of said other lever and a supporting surface at said one lever and upon actuation adapted to press apart the end of said other lever and the supporting surface, whereby the levers can be pivoted towards one another in the sense of movement of the fastening pins.
