Abstract: C-arm retention locks allowing users to secure and unsecure C-arm positioning devices of an X-ray machine, systems containing such locks, and methods of using such locks are described. The C-arm retention lock comprises a latch bail and a latching assembly. The latching assembly comprises a latch base having an ear and a generally flat engagement surface at an end of the latch base proximate the ear, a latch having an arm, the latch being pivotally connected to the latch base so the latch is rotatable between closed and open positions, and a tensioning device engaging the latch and latch base such that the tensioning device pulls the latch toward either of the closed or open positions. The latching assembly or latch bail is configured to be connected to a C-arm and the latching assembly retains the latch bail between the ear and the arm when the latch is closed.
