Spacer device for a carrier system for a motor vehicle, comprising a spacer element which is elongated along its longitudinal axis between its first end face and its second end face, a fastening device, which is arranged at the first end face and is provided for fastening a frame profile of a load, a clamping device, which is arranged at the second end face and is configured for clamping to a support profile of the carrier system that can be positioned in a fixed position on the vehicle, wherein the clamping device can be displaced relative to the spacer element between a clamping position for clamping to the support profile and a release position for releasing from the support profile, and wherein the clamping device has at least a first clamping jaw and a second clamping jaw, which can each be pivotably displaced about a pivot axis (12, 13) relative to the spacer element in order to displace the clamping device between the clamping position and the release position, and having an adjusting device with a screw gear (14, 15) which is operatively connected at one end to the clamping device and by means of which a manual rotary actuating movement acting on the spacer device can be translated into a displacement movement of the clamping device between the clamping position and the release position, characterized in that a bearing device is provided, by means of which the clamping device and the spacer element are mounted on one another so as to be rotatable relative to one another about the longitudinal axis, and in that the screw gear (14, 15) is operatively connected at the other end to the spacer element, whereby manual rotation of the spacer element about the longitudinal axis causes the displacement movement of the clamping device between the clamping position and the release position. a spacer element which is elongated along its longitudinal axis between its first end face and its second end face, a fastening device, which is arranged at the first end face and is provided for fastening a frame profile of a load, a clamping device, which is arranged at the second end face and is configured for clamping to a support profile of the carrier system that can be positioned in a fixed position on the vehicle, wherein the clamping device can be displaced relative to the spacer element between a clamping position for clamping to the support profile and a release position for releasing from the support profile, and wherein the clamping device has at least a first clamping jaw and a second clamping jaw, which can each be pivotably displaced about a pivot axis (12, 13) relative to the spacer element in order to displace the clamping device between the clamping position and the release position, and having an adjusting device with a screw gear (14, 15) which is operatively connected at one end to the clamping device and by means of which a manual rotary actuating movement acting on the spacer device can be translated into a displacement movement of the clamping device between the clamping position and the release position, characterized in that a bearing device is provided, by means of which the clamping device and the spacer element are mounted on one another so as to be rotatable relative to one another about the longitudinal axis, and in that the screw gear (14, 15) is operatively connected at the other end to the spacer element, whereby manual rotation of the spacer element about the longitudinal axis causes the displacement movement of the clamping device between the clamping position and the release position.
