a tapering recess formed in, or connected to, the first piece, the tapering recess has an opening which is shaped and dimensioned to receive a wedge formed in, or connected to, the second piece, the wedge has a dovetail profile which is adapted to engage with walls of the recess, and the wedge is shaped and dimensioned to slide in a first direction and thereby wedge into the tapered recess;
