a generally triangular clamp, including:
a first side between a first vertex and a first mouth end;a second side between a second vertex and a second mouth end; anda third side between the first vertex and the second vertex; a catch arm pivotably connected to the first mouth end, the catch arm including a linear segment having a catch width, the linear segment being parallel to the third side and being distal from the first mouth end; and a hook arm pivotably connected to the second mouth end, the hook arm including a hook configured for secure but releasable connection around a linear segment of a matching binder clip, the hook having a hook width less than the catch width of the linear segment; wherein the first side, the second side, and the third side cooperate to bias the first mouth end toward the second mouth end for clamping items between the first mouth end and the second mouth end, and wherein pivoting the catch arm against the first vertex and pivoting the hook arm against the second vertex separates the first mouth end from the second mouth end to admit items for clamping between the first mouth end and the second mouth end. |
