A control mechanism for use with a hydraulic locking device to permit the device to be unlocked under control of an operator. The control mechanism includes a lever assembly fastened to the piston rod of the hydraulic control device and connected by a cable to a remotely located push button assembly. When the operator presses the push button, the cable is drawn causing the lever assembly to move an operating rod of the hydraulic locking device to a release position thereby unlocking the device. The lever assembly can be installed on the hydraulic locking device without the use of tools by sliding a spring clip which is a non-removable portion of the lever assembly. A threaded collar permits the effective length of the conduit to be altered to adjust the stroke of the mechanism. The spring cip is made to serve a dual purpose. When the spring clip has been shifted to the position in which it secures the lever assembly to the hydraulic locking device, the spring clip in that position also locks the threaded collar from rotating. When the spring clip has been shifted to its other position, the threaded collar may be rotated.
