Abstract: A raised toilet seat has a front part (2) and two wings (3, 4) of which the ends are, before the raised seat is fitted, separated by a gap. The wings (3, 4) at their free ends bear, in the case of one of them (3), a channel section equipped with notches (9, 10), and, in the case of the other (4), an opening (12) to accept the channel section, and ridges (13, 14, 15, 16) to retain the notches (9, 10).
