Abstract

A gas spring with a center longitudinal axis including a cylinder includes a piston in the cylinder that divides the cylinder into a first cylinder chamber and a second cylinder chamber. A piston rod is arranged at the piston guided out of the cylinder at a second end opposite the first end. A connection element with a socket housing is arranged at each of the first end and the free end of the piston rod for receiving a ball head. At least one of the two socket housings comprises a ball socket with a longitudinal extension and a transverse dimension, the longitudinal extension is greater than the transverse dimension. A catch element having a spring tongue is arranged at the first end for insertion together with the catch element into a cover tube that locks into a recess associated with it in the cover tube.
