1. A surgical tool comprising:
an inner drive hub coupled to an inner shaft, the inner drive hub further comprising a boss;
an outer hub coupled to a hollow outer shaft, the outer drive hub further comprising at least one hole; and
a seal comprising a body and at least one tab;
wherein the inner drive hub and the inner shaft are configured for insertion inside the outer hub and the hollow outer shaft such that the boss is positioned distally to the at least one hole; and
the seal body is positioned outside of the outer hub and the at least one tab extends through the at least one hole and proximally to the boss to removably couple the inner drive hub and the inner shaft to the outer hub and the hollow outer shaft;
wherein the at least one tab cooperates with the inner drive hub to prevent the inner drive hub from being removed from the outer hub without removing the seal; and
wherein if the inner drive hub is pulled outward from the outer hub, the boss forces the at least one tab to bend and become wedged between the boss and the outer hub, thereby preventing the boss from moving past the tab and preventing the inner drive hub from being withdrawn from the outer hub.
