ABSTRACT:
A toothbrush includes a brush part and a hollow handle part exhibiting an axial bearing, a coupling rod, which is slidably mounted in the axial bearing and which is connected to the brush part, a return spring, which is pretensioned on the coupling rod in the direction of the handle part opposite the brush part, and a latching device for rotationally locking the coupling end of the brush part and the coupling end of the handle part. A securing device serves to prevent axial motion of the coupling rod. A first part of the securing device is associated with the coupling rod and a second part of the securing device is associated with the handle part. The second part of the securing device is movable between a securement setting and a release setting and is pretensioned by a spring in the direction of the securement setting. An actuating device in the wall of the handle part serves to actuate the second part of the securing device. An axial motion of the brush part relative to the handle part, for releasing the rotationally secure connection of the two parts, is therefore reliably prevented.
