Tube coupling has a first part (3) connected to a first tube. A second part includes a pin (4). The first part is hook-shaped at the end, with entry (6) for the pin. The coupling has a connecting part (7) from part (3) between the entry of pin (6) and the connection of the first tube at the side of the pin. The outer part (8) in the coupled position, joins with the second tube to the internal part of the second tube.
