Abstract: A plug-in connector has a plug member and a locking device for securing the plug member on a counterpart. The locking device has at least one locking element having a release position and a locking position, wherein in the release position the plug member is removable from the counterpart and wherein in the locking position the plug member and the counterpart are locked relative to one another. An actuating element acting on the locking device is provided for moving the at least one locking element from the release position into the locking position in a radial direction relative to a longitudinal axis of the plug member.

Abstract: There is provided a car jack comprising a column attached at its bottom to a base, and a load-carrying arm pivoted to the column and movable by a screw spindle. The screw spindle is pivotably supported by a nut at the top of the column and by an abutment of the load-carrying arm. The arm and the column are formed from metal sections of U-shaped cross-section with the edges of the side limbs outwardly bent. Each of the outwardly bent parts is formed as a bead extending along the entire length of the side limb with its edge disposed in the plane of the internal flat side of the respective limb.
