Connectors for peritoneal dialysis

A connector assembly configured to connect a tube to a peritoneal dialysis cycler, the connector assembly comprising:

• a connector piece having a proximal portion and a distal portion and having a bore extending longitudinally therethrough, wherein a proximal end of the bore of the connector piece defines an opening in the proximal portion of the connector piece configured to receive and deliver fluid from and to the peritoneal dialysis cycler, and wherein a distal end of the bore defines an opening in the distal portion of the connector piece;
• and
• a connector body having a proximal portion and a distal portion and having a bore extending longitudinally therethrough, wherein a proximal end of the bore of the connector body defines a cavity in the proximal portion of the connector body configured to receive the distal portion of the connector piece to position the distal end of the bore of the connector piece in fluid communication with the proximal end of the bore of the connector body, the distal portion of the connector body comprising a tubular portion configured to form an interference fit with an end of the tube, and wherein the connector body further comprises a distally extending collar configured to grip an outer surface of the tube when the tube forms the interference fit with the tubular portion,
• wherein an inner surface of the distally extending collar of the connector body is free of threading,
• wherein the distal portion of the connector piece defines a distally tapered surface extending to a distal end of the connector piece,
• wherein the distal portion of the connector piece defines a cylindrical skirt portion radially outwards of the distally tapered surface and extending to the distal end of the connector piece, the cylindrical skirt portion defining a mating surface configured to releasably secure the connector piece to the connector body, and
• wherein the connector piece has an overall substantially cylindrical outer surface contiguous with and having a same diameter as the cylindrical skirt portion.
