Abstract: A connecting component for connecting different scaffolding systems, comprising at least a first connection region, which is provided for connection to a first scaffolding system and which has a shaft that extends along a longitudinal axis, and an attachment region which is provided for connection to a second scaffolding system, wherein the first connection region and the attachment region are arranged adjacent to one another in the direction of the longitudinal axis and the first connection region has a receptacle in its interior in the shaft, at least on its side pointing away from the attachment region, which extends in the direction of the longitudinal axis. The attachment region has an abutment adjacent to the first connection region extending in a direction essentially perpendicular to the longitudinal axis, and the abutment has the longest dimension of the attachment region in the direction essentially perpendicular to the longitudinal axis.
