Double connector for butt-joining two parts

A double connector for butt-joining two components, the double connector comprising:

• two connector components which can be pushed together as far as a locked assembly position and which each connector component comprises:
• a spreadable first end portion for inserting into a hole of a component;
• a second end portion for spreading the first end portion of the other connector component in each case in the assembly position;
• and
• at least one locking portion for interlocking the two plug components in the assembly position;
• wherein the two connector components are each constructed as a U-shaped clamp having two outer clamp arms which can be spread with respect to each other and having a central clamp arm which is located there between;
• wherein the thickness of the central clamp arm transversely with respect to the spreading direction of the two outer clamp arms is greater than the clear spacing of the two free clamp ends.
