Abstract (en)
[origin: US4914791A] A plastic paper clip having two outer, approximately V-shaped clamping legs connected by transverse webs to a pair of clamping arms disposed within the clamping legs, has a longitudinal slot terminating at an extension element leading to the clamping arms. The extension element is not slotted. When applied to clip paper, the clip is subjected to torque in the area of the longitudinal slot, but the extension element keeps the torque from deforming the clamping arms.
