  • Patent number: 5432982
    Abstract: A clip for retaining together sheets of paper or other materials comprising a single thin strip of resilient sheet-like material bent upon itself to define an end fold and first and second holding legs each having first and second upper ends respectively interconnected at said end fold, said first and second holding legs each having first and second lower ends respectively opposite said end fold and said lower ends intersecting at an angle with respect to each other so as to define a reverse V-shaped push-on space and wherein at the position where the two push-on edges cross each other a space is created between the legs as a result of the fact that at least one of the clamping legs is provided with a non-angular depression.

  • Patent number: 5357653
    Abstract: Clip for holding and/or keeping together sheets of paper or other materials, comprising two holding elements lying essentially in parallel planes and springing relative to each other, and of which the two end edges run parallel at a distance from each other or at an angle relative to each other, and form push-on edges when in use. According to the invention, the two holding elements are in the form of holding legs (1, 2) of sheet-type material, and one (2) of said holding legs is bent in such a way that a part (4, 6) adjacent to the connecting line (3) with the other leg (1) lies at a distance from said other leg, and a second part (8), essentially ending at the push-on edge (13), lies with at least a part of its inside essentially flat and resiliently against the inside of a part (9) of the other holding leg (1). The clip can also be placed on other objects of different types.
