ABSTRACT:
A simple twist and lock or unlock structure is provided for use with high pressure hydraulic lines used on small vehicles such as Lawn and Garden tractors. The locking structure utilizes the combination of a tab and slotted member secured to adjacent end portions of the hydraulic lines to releasably secure them together. No tools are required to rotatably manipulate the locking structure into its locked or unlocked position. With this structure, no clamping hardware is needed to secure the lines together nor are any anchoring brackets required to mount the lines to the vehicle or its components. Accordingly, leaks caused by engine vibrations or vehicle encounters with small obstacles are minimized.
