1. A system, comprising:
a locking device, comprising:
a housing including a top surface, a bottom surface, and a side portion disposed between the top surface and the bottom surface;
a cutout disposed through the housing from the top surface to the bottom surface, the cutout at the bottom surface sized and shaped to accommodate a port of a dialyzer, and the cutout at the top surface sized and shaped to accommodate one or more of (i) an outer diameter of tubing of an extracorporeal circuit of a dialysis system, and (ii) an outer diameter of a first end of a connector configured to couple the tubing to the port of the dialyzer, wherein a second end of the connector is configured to releasably secure the connector to the port of the dialyzer;
an interior void within the side portion between the top surface and the bottom surface of the housing, the interior void having a maximum diameter larger than a maximum width of the cutout, the interior void sized and shaped to accommodate winged portions disposed between the first and second ends of the connector; and
a first engagement portion disposed on the bottom surface of the housing; and
a second engagement portion on an end of the dialyzer that includes the port, the second engagement portion disposed on an adapter couplable to the dialyzer, wherein the first engagement portion and the second engagement portion are couplable such that the winged portions of the connector are mitigated from rotating relative to the end of the dialyzer thereby securing the connector in a substantially fixed rotational position.
