1. A locking assembly for securing a wear member to a support structure, the locking assembly comprising:
a locking pin having a pin axis and comprising a first pin portion and a second pin portion that are spaced along the pin axis, the pin portions being interconnected through a coupling configured to allow torque to be transferred from at least one of the first or second pin portions to the other of the first or second pin portions and allow axial movement of one of the pin portions relative to the other pin portion in the direction of the pin axis; wherein the coupling is in the form of complementary coupling elements that interfit and extend in the direction of the pin axis, the coupling elements of the first and second pin portions are angularly spaced apart about the pin axis, and wherein the coupling elements of the first pin portion are arranged to be angularly offset from the coupling elements of the second pin portion so as to interfit with one another to form the coupling.
