An introducing device serves to introduce instruments into a living body. A trocar pipe is fastened to a housing. The housing contains two axially aligned channels between which a sealing slide is arranged. The slide has a passage opening that may be aligned with the channels in order to pass an instrument of corresponding diameter therethrough. In the slide, an auxiliary slide is provided that has a passage opening of smaller diameter. When the auxiliary slide is advanced in the slide, its passage opening gets into the area of the passage opening of the slide and reduces the same. Thus, the diameter of the passage opening can be adapted to that of the instrument used so that the location of passage is sealed.
