1. A bone fixation plate assembly, comprising:
a bone fixation plate including a fastener hole and a clip cavity adjacent to the fastener hole; and
a locking clip comprising:
a flexure member and situated at least in part in the clip cavity; and
a locking tab having a convex shape extending inward relative to the flexure member;
wherein the flexure member is resiliently flexible to permit displacement of the locking tab to allow passage of a fastener head of a fastener; and
wherein the locking tab is configured to provide an axial limitation to motion of the fastener in a non-rotationally-ratcheting manner.
