<p>The bolt is displaceably located against spring force in relation to the thin wall (12). The bolt is formed by a second trough (18) which is displaceably located in the first trough (14) held in the first trough in the thin wall and against the force of a spring (20). The first trough has a nose formation (26) projecting over the outer wall plane (24). The nose formation, when the first trough is pressed into the cut-out (16) of the thin wall, can be switched back in the wall plane against spring force, forming a surface (30) which clamps on the inner surface or edge of the cut-out.</p> |
