ABSTRACT:
An interdental tooth-brush includes a support bar (1) with a transversal hole (2a) at one end, a small brush stick (3) with a filiform projection (3a) apt to engage into the transversal hole (2a), and a retention device to fix the projection (3a) into the transversal hole (2a) in an interchangeable manner. The transversal hole (2a) is formed into a support head (2) provided at the end of the support bar (1). This support head (2) has a protuberance projecting through a slot (4a) of a cap (4) fitted onto the support head (2). The cap (4), having two diametrically opposite slots (4a, 4b), is axially slidable between a position of release, in which both slots (4a, 4b) are aligned with the transversal hole (2a), and a locking position, in which the rear slot (4b) is axially offset with respect to the hole (2a ).
