A device for checking the seal-tightness of closure caps on medical hollow bodies has a drive, a retaining element for the hollow body, and a retaining device for the closure cap. The retaining device is pivotably supported relative to the retaining element. The device further includes a sensor for the relative rotation of the retaining device with respect to the retaining element. A torque may be applied to the closure cap by the drive, the retaining element, and the retaining device. A hollow body and a closure cap are gripped by the retaining device and the retaining element from the same side, as viewed along the longitudinal axis of a hollow body.
