The invention relates to an adjustable stroke gas spring, formed by a tight cylindrical chamber (1), in which there is housed a piston, the stem (2) of which projects coaxially through one of the bases of the chamber. The spring comprises a cylindrical sheath (3) arranged and fixed around the wall of the chamber, a guide (4) assembled transversely on said sheath, with the ability of sliding and anchoring therealong, and a locking rod (5) parallel to the stem, which rod is assembled is assembled between the free end of said stem and the guide, with the ability of sliding with respect to said guide. The cylindrical sheath and guide have releasable mutual anchoring means along at least one section of the sheath for fixing the guide on the sheath in the selected position. The rod is fixed at one end to the end of the stem and at the opposite end it is finished in a stop located outside the guide preventing the separation of said guide.
