A novel multi-purpose clip or clamp device and improved paper clip which can grip multiple pieces or sheets of material, consisting of a length of resilient material, such as but not limited to spring wire, bent to form a "U" shape lower clamping arm loop with each end bent at slightly different lengths to laterally crisscross each other in the same plane to act as dual spring interconnecting legs and then bent in the same plane to provide dual upper clamping arms. The material is clipped or clamped in between the lower and upper arms that lay flat on the clamped material without distortion, while bending the dual interconnecting spring legs to expand and contract to the variations in material thickness, thereby providing a constant clamping pressure for a wide range of material thickness.
