Abstract
A mechanical locking device for restraining the piston rod of a gas spring n an extended position comprises a lock tube mounted on the piston rod coaxially with the cylinder and adapted to ride telescopingly over the cylinder during normal inward and outward movement of the piston rod. Apparatus is provided on the piston rod whereby the piston rod can be overextended, beyond its normal fully extended position, to permit the lock tube to move out of coaxial alignment with the cylinder; the end of the lock tube thereby abuts the end face of the cylinder and prevents inward movement of the piston rod.
