Claim:
1. A lancing device for taking blood samples, comprising: a housing which extends along a longitudinal axis from an end region of the lancing device to a head region of the lancing device, an axially displaceable lancet holder element for holding a replaceable lancet, a drive unit comprising at least a lancing spring element for driving the axially displaceable lancet holder element in a lancing direction, a fixable tensioning carriage part for tensioning said lancing spring element, and a further tensioning carriage part by which said fixable tensioning carriage part is able to be displaced from a relaxed position at the end region of the lancing device in the lancing direction towards the head region of the lancing device to a tensioning position, wherein said fixable tensioning carriage part is able to be fixed in this tensioning position, wherein by said displacement of the fixable tensioning carriage part the lancing spring element is able to be tensioned, wherein the fixable tensioning carriage part is axially fixed in the tensioning position by means of a latching apparatus which is able to be latched to the axially displaceable lancet holder element, wherein the entire displaceable lancet holder element and the entire fixable tensioning carriage part are displaceable relative to each other along said longitudinal axis, wherein the further tensioning carriage part comprises an engagement element for radial engagement of the latching apparatus which is able to be latched to the axially displaceable lancet holder element.
