The system comprises a junction element that is provided for connecting three elongated frame elements (24,26,28) through two retaining webs (30,32). The abutment surface (34,36) for the respective end surfaces (72,74) of the frame elements are arranged on the outer side of the webs. A receptacle (38) which receives two side surfaces of the frame elements is formed between the webs. Each end surface of the frame elements is formed of a recess complementary to the abutment surface to receive the respective webs, such that the webs are flushed with the end surfaces. |
