Abstract
The invention provides a telescopic member that includes a cylinder in which a rod carrying a piston is mounted to slide telescopically, the telescopic member including internal abutment mechanisms that are overridable over a predetermined force when the rod comes into abutment inside the cylinder in the shortening direction. The internal abutment mechanisms include an abutment piece extending in an open bore within the rod and projecting therefrom, the abutment piece being held to the rod via a pin.
