A distributor for a plate heat exchanger, comprising:

• a tube part, having a tube wall and having a first end and a second end, with a tube part inner cavity being defined in the tube part;
• a first flange formed at the first end, the first flange extending from the first end in a direction away from an axis of the tube part, the first flange having an outer edge remote from the tube part;
• and
• a connecting protrusion, projecting from the tube wall of the tube part in a direction away from the axis of the tube part, and projecting from the first flange at the inside of the outer edge of the first flange in a direction towards the second end of the tube part;
• the connecting protrusion having a connecting protrusion wall, with a connecting protrusion inner cavity being defined in the connecting protrusion wall, the connecting protrusion inner cavity being in communication with the tube part inner cavity;
• the connecting protrusion wall having an axial connecting protrusion wall which faces in the axial direction of the tube part and is remote from the first flange, the axial connecting protrusion wall being between the first end and the second end of the tube part, and having at least one through-hole.
