Abstract
A lockable gas spring arrangement includes a gas spring with a closed cylinder, a displaceably guided piston and piston rod. A fastening tube fastened with its one end in the region of the free end of the piston rod and on which a locking element is arranged. The locking element is able to be moved substantially radially to the piston rod between an unlocked position permitting a free insertion movement and a locked position bearing against the front face of the cylinder on the piston rod side when the piston rod is extended. The locking element is able to be urged by a spring into its locked position. The locking element is able to be moved manually from its locked position into its unlocked position and is able to be retained automatically in its unlocked position by a retaining device.
