Connection unit i.e. clip, for connecting two plates with each other, has head deformable elastically perpendicular to its contact surface, such that head is brought under pre-stress and barbs are brought in rear contact to undercut

摘要

The unit (1) has a head (2) with a contact surface, and barbs (5, 6) that are attached to the head with perpendicular distance from the contact surface of the head. The head is deformable elastically perpendicular to its contact surface, so that the head is brought under pre-stress by elastic deformation of the head and the barbs are brought in rear contact to an undercut. The undercut is placed at a distance from the contact surface of the head.
