Toothbrush having a brush part (32) and a hollow handle part (34) exhibiting an axial sliding bearing (40), a coupling rod (36), which is axially displaceable in the handle part (34) and can be connected to the brush part (32) and juts into the hollow handle part, further having a return spring (86), which is pretensioned on the coupling rod (36) in the direction of the handle part (24), and a latching device (46, 48) for a twist- prevention securement between the coupling end of the brush part (32) and of the handle part (34). A securing device (88) serves to prevent an unintended axial motion of the coupling rod (36). A first part of the securing device (locking block 82) is assigned to the coupling rod (36) and a second part of the said securing device (locking lever 90) is assigned to the handle part (34). The second part is movable between a securement setting and a release setting and is pretensioned by means of a spring (98; 238) in the direction of the securement setting. An actuating device (elastic wall segment 120; elastic endpiece 248) in the wall of the hollow handle part (34) serves to actuate the second part of the securing device (88). An axial relative motion of the brush part relative to the handle part, for releasing the rotationally secure connection of the two parts, is hereby reliably prevented. (Fig. 2) |
