Tube connector for medical tube lines

A tube connector for medical tube lines, the tube connector comprising:

• a body having a first end and a second end;
• a first mating section arranged at the first end and configured for axial insertion into a first tube end of a first medical tube line along a first mating axis;
• a second mating section arranged at the second end and configured for axial mating with a second tube end of a second medical tube line along a second mating axis;
• and
• a connecting lumen which is elongate between the first end and the second end through the body,
• the connecting lumen forming a fluid connection between a first opening in the first mating section and a second opening in the second mating section,
• the body comprising at least one blade section which is assigned to the first mating section and a cutting edge oriented in a direction of the first mating axis, and
• the first tube end of the first medical tube line being axially slitable by the cutting edge upon insertion of the first mating section,
• wherein the body is made of a plastics material in one piece.

A catheter arrangement comprising:

• a first catheter tube;
• a second catheter tube;
• a tube connector comprising:
• a body having a first end and a second end,
• a first mating section arranged at the first end and configured for axial insertion into the first catheter tube along a first mating axis,
• a second mating section arranged at the second end and configured for axial mating with the second catheter tube along a second mating axis, and
• a connecting lumen which is elongate between the first end and the second end through the body,
• the connecting lumen forming a fluid connection between the first catheter tube and the second catheter tube,
• the body comprising at least one blade section which is assigned to the first mating section and a cutting edge oriented in a direction of the first mating axis, and
• a tube end of the first catheter tube being axially slitable by the cutting edge upon insertion of the first mating section into the first catheter tube;
• and
• a fixing section fixing the connection between the first catheter tube and the second catheter tube.
