Connecting elements for arranging two wall elements together

1. A connector configured to couple plural wall panels, the connector comprising:

a coupling including a first support that supports a locking hook that is pivotable from an idle position into an engagement position and movable into an interlocking position;

a block including a locking bar that is arranged in a second support wherein the locking hook reaches behind the locking bar in the locking position; and

a respective housing for each of the coupling and the block, the respective housing including a housing pass through opening wherein the locking hook passes through the housing pass through opening during a pivot movement from the idle position to the engagement position,

wherein the respective housing includes a first housing half and second housing half,

wherein the housing pass through opening of the coupling and the block is closed by a cover wall against a pass through of the locking hook and openable by the pivot movement of the locking hook from the idle position to the engagement position,

wherein the cover wall is provided integrally in one piece by at least one of the first housing half and the second housing half so that a penetration of a foam material into the respective housing is prevented when the block or the coupling is encased in a wall panel by the foam material,

wherein the respective housing includes a tool opening through which a tool is insertable that is configured to pivot the locking hook, and

wherein the tool opening is closed by a closure wall so that a penetration of the foam material into the respective housing is prevented when the block or the coupling is encased by the foam material in the wall panel.

2. The connector according to claim 1 ,

wherein the cover wall or the closure wall includes weakened material zones, and

wherein the cover wall or the closure wall are breakable along the weakened material zones.

3. The connector according to claim 1 ,

wherein a support structure is provided for the cover wall, and

wherein the support structure is formed by another of the first housing half and the second housing half.

4. The connector according to claim 1 ,

5. The connector according to claim 1 , wherein an entire configuration of the first housing half of the coupling is structurally identical to an entire configuration of the first housing half of the block and an entire configuration of the second housing half of the coupling is structurally identical to an entire configuration of the second housing half of the block.

6. A connector configured to couple plural wall panels, the connector comprising:

a coupling including a first support that supports a locking hook that is pivotable from an idle position into an engagement position and movable into an interlocking position;

a block including a locking bar that is arranged in a second support wherein the locking hook reaches behind the locking bar in the locking position; and

a respective housing for each of the coupling and the block, the respective housing including a housing pass through opening wherein the locking hook passes through the housing pass through opening during a pivot movement from the idle position to the engagement position,

wherein the respective housing include a first housing half and a second housing half,

wherein the housing pass through opening of the coupling and block is closed by a cover wall against a pass through of the locking hook and openable by the pivot movement of the locking hook from the idle position to the engagement position, and

wherein the cover wall is provided integrally in one piece by at least one of the first housing half and the second housing half so that a penetration of a foam material into the respective housing is prevented when the block or the coupling is encased in a wall panel by a foam material.

7. The connector according to claim 6 ,

wherein the cover wall includes weakened material zones, and

wherein the cover wall is breakable along the weakened material zones.

8. The connector according to claim 6 ,

wherein a support structure is provided for the cover wall, and

wherein the support structure is formed by another of the first housing half and the second housing halt.

9. The connector according to claim 6 ,

wherein the locking hook includes a breakthrough protrusion oriented in the pivot direction that breaks the cover wall when the locking hook pivots into the engagement position.

10. The connector according to claim 6 , wherein an entire configuration of the first housing half of the coupling is structurally identical to an entire configuration of the first housing half of the block and an entire configuration of the second housing half of the coupling is structurally identical to an entire configuration of the second housing half of the block.

11. A connector configured to couple plural wall panels, the connector comprising:

a coupling including a first support that supports a locking hook that is pivotable from an idle position into an engagement position and movable into an interlocking position;

a block including a locking bar that is arranged in a second support wherein the locking hook reaches behind the locking bar in the locking position; and

a respective housing for each of the coupling and the block, the respective housing including a housing pass through opening wherein the locking hook passes through the housing pass through opening during a pivot movement from the idle position to the engagement position,

wherein the respective housing includes a first housing halt and a second housing half,

wherein the housing pass through opening of the coupling and the block is closed by a cover wall against a pass through of the locking hook and openable by the pivot movement of the locking hook from the idle position to the engagement position,

wherein the respective housing includes a tool opening through which a tool is insertable that is configured to pivot the locking hook, and

wherein the tool opening is closed by a closure wall so that a penetration of a foam material into the respective housing is prevented when the block or the coupling is encased by, the foam material in a wall panel.

12. The connector according to claim 11 ,

wherein the cover wall or the closure wall includes weakened material zones, and

wherein the cover wall or the closure wall are breakable along the weakened material zones.
