Abstract: A gas pressure spring comprising a housing having a gas-filled interior, a longitudinal axis, a closed housing end and an open housing end which is situated opposite the closed housing end. The gas pressure spring additionally includes a piston rod which is displaceable along the longitudinal axis and is guided out of the housing in a sealed manner through the open housing end, a piston unit which is fastened on the piston rod and a damping unit for damping the displacement of the piston unit.

Abstract: A gas spring has a housing closed at one end and a piston rod brought out of the other end of the housing. The housing is detachably mounted in a surrounding tube and is able to be pushed into the latter as far as an end position. Securing elements are mounted respectively at the outer end of the piston rod and on the surrounding tube. So as to ensure that a part supported by the gas spring is reliably held also when the housing is partly pulled out of the surrounding tube a locking element for the detachable locking of the housing with the surrounding tube is provided in an intermediate position in which the housing respective to the end position is partly pulled out of the surrounding tube.
