ABSTRACT:
A clip for securing together a stack of sheets, the stack having a height, or thickness, which can vary over an extended range, the clip having opposed clamping legs spaced apart and extending parallel to one another, a web interconnecting the clamping legs at corresponding ends of the clamping legs, and resiliently deflectable undulations in the web allowing relative displacement of the clamping legs away from one another to receive the stack between the clamping legs and biasing the clamping legs toward one another with a biasing force sufficient to secure the stack, while the clamping legs remain parallel to one another.
