A connection system for attaching a damping unit of a vehicle inside of a wheel suspension of the vehicle, wherein the connection system has an upper attachment region for attaching the damping unit, wherein the attachment region at least partially surrounds a receiving area for the damping unit, wherein the receiving area extends about a first axis which is the damping axis of the damping unit, a lower attachment region for coupling to the wheel-side part of the wheel suspension, wherein the lower attachment region includes two lower sections spaced apart from one another with an attachment space therebetween, and an intermediate region, which connects the upper attachment region to the lower attachment region, wherein a main extension of the intermediate region corresponds to the direction of the first axis, and wherein a free space of the intermediate region enables the passage of a drive shaft of the vehicle, characterized in that the connection system is manufactured from an extruded part, whose extrusion direction is the extension direction of the extruded material, which then forms the intermediate region of the connection system, wherein the axial extension of the upper attachment region along the first axis is larger than 1.2 times the smallest transverse dimension of the intermediate region with respect to the first axis, and wherein the free space is formed at least partially by a cutout of extruded material underneath the extruded material that forms the upper attachment region.
