An insertion apparatus for use in a vaginal or rectal cavity or a vaginal or rectal opening of the human body. The insertion apparatus has a base body, which in turn has a working body. In addition, a pulling device used for removing the working body from the cavity or the opening is firmly mounted on the base body. The pulling device is formed by a finger grip that is elastically formed, at least in part. The finger grip is elastically deformable between a neutral position and a removal position, and the finger grip is made, at least in part, of an elastic material. The insertion apparatus may in particular be configured as a massage apparatus or as a tampon.
