First Claim
1. A connection unit, between a support, including a body part of a motor vehicle, and a plate element, including one of a door and a wall face, comprising:
- a connection element having an upper piece attachable to the plate element and a lower piece connectable with the support;
a neck-shaped intermediate zone between the upper piece and the lower piece;
locking elements located along the intermediate zone and penetrating into a support opening of an embeddable contact piece;
a casing part surrounding the intermediate zone above the support, the casing part being lockable with the locking elements and the contact piece; and
a sealing element between the casing part and the embeddable contact piece engaging a surface of the support.

Abstract
A connection element (1) between a support (2), specifically a body part of a motor vehicle, and a plate element, specifically a door or wall facing. The connection element (1) includes an upper piece (3) attachable to the plate element and a lower piece (4) connectable with a support (2). A neck-shaped intermediate region (5) is provided between the upper part (3) and the lower part (4). The intermediate region (5) is equipped with locking elements (10) and penetrates into a support opening (7) embeddable contact piece (12). The intermediate region (5) above the support (2) is surrounded by a casing part (15), which is lockable with the locking elements (10) and the contact piece (12). A sealing element (20), which acts upon the surface of the support (2), is arranged between a casing piece (15) and a contact piece (12).
