A closing device for a sliding door device with at least one sliding door, comprising a device body, a first roller set that is held displaceable, a second roller set that is held stationary by the device body, a tension spring, which is connected by a first spring end piece directly or indirectly to the first roller set and which is connected by a second spring end piece directly or indirectly to the second roller set, and a pull rope, which is guided with several loops around the first roller set and the second roller set and which is connected with a first rope end piece directly or indirectly to the first roller set or to the device body and which is led out of the closing device with a second rope end piece, wherein,

that the device body comprises a holding rail, which displaceably holds a roller carriage that comprises a carriage body,
that the roller carriage is coupled to the first spring end piece and is provided with a first mounting shaft by which the first roller set is rotatably supported,
that the device body is integrally, force-fittingly or form-fittingly connected to a connection device which is connected or connectable to a drive body of a drive unit, and
that the connection device by means of a bearing shaft rotatably holds a deflection pulley around which the tension spring is guided.
