| 摘要 |
The invention is related to a device for mutually interlocking a first element (1) provided with a recess (3) and a second element (2) so that they form an angle with each other. The device comprises a body (40) having a protrusion (41) adapted to be insertable in the recess (3) in the first element and means (42, 4, 7) for attaching the second element (2) to the body. Said attaching means is designed tightenable and adapted to, when being tightened, apply a force on the protrusion (41), which is inserted in the recess (3) in the first element (1), so that the protrusion puts a load on the first element (1) substantially only in direction towards the second element, one of the boundary edges (81) of the first element being pressed against one side (82) of the second element and thereby mutually interlocking the two elements. |
