A binding element for binding a stack of documents comprised of loose sheets, comprising:
- a spine piece;
- and
- two spaced apart side pieces arranged substantially perpendicular to said spine piece and being, in use, biased toward each other at room temperature, thereby generating a clamping force for binding the plurality of sheets between the side pieces;
- wherein the binding element comprises a shape memory material such that the side pieces are moved away from each other when the binding element is heated to a predetermined temperature above room temperature, thereby reducing the clamping force to facilitate removal of one or more of the sheets or addition of one or more extra sheets.

- a spine piece;
- two spaced apart side pieces arranged substantially perpendicular to said spine piece and being, in use, biased toward each other at room temperature thereby generating a clamping force for binding the plurality of sheets between the side pieces;
- and
- a component comprising shape memory material engageable with the side pieces, such that the side pieces are moved away from each other when said component is heated to a predetermined temperature above room temperature, thereby reducing the clamping force to facilitate removal of one or more of the sheets or addition of one or more extra sheets.
