Two members are locked together by forcing wedge means between mutually facing and converging surfaces of the members, the wedge means causing gripping means to engage one of the members to lock the members together. A fluid pressure is established between the wedge means and at least one surface of one of the members while forcing the wedge means into wedging position between the members to minimize friction between the wedge means and the elements with which they are in contact during movement. When the wedge means is in position, the fluid is terminated to complete the lock. |
