1. A rotatable connector (200) formed from two parts (100), each part comprising: a body (20) extending from a connecting head (10), the bodies (20) of the two parts (100) being identical; wherein the connecting head (10) has a first face (11) and an opposed second face (12), characterized in that the second faces of each part (12) include an arcuate tail section (13) arranged on an outer perimeter edge of a segment of each connecting head (10) and each second face is shaped and dimensioned to be received through a tail socket (30) defined between the first face (11) and a pin (40) extending from a proximal end of the body (20); so that when the two first faces (11) abut each other, the two parts (100) are engaged as engaged parts (100) and the two connecting heads (10) are coaxial to define an axis of rotation, and when the engaged parts (100) are rotated relative one to another, the tail section (13) of the first part travels through the tail socket (30) of the second part and the tail section (13) of the second part travels through the tail socket (30) of the first part, thereby connecting the two parts (100) together; and when the two parts are rotated in an opposite direction, the two parts are disconnected one from the other.
