ABSTRACT:
The invention relates to a control device for a gas spring which can be locked as desired by displacement of a sliding control finger. Two axially elongated, diametrically opposed windows (14), at least one of which is larger at the end nearest to the gas spring, pass through a tubular connector (1) coaxial with the control finger (6). A lever (2) which has thinner parts (25, 26) flanking a wide part (24) engages in these windows. Devices (7) are provided so that, after mounting on the gas spring, the wide part (24) is unable to reach the wide section of the window, thus preventing the lever from being dislodged. The edges of the windows (14) form bearing points for the pivoting movement of the leaver and the actuation of the control finger (6).
