| 摘要 |
The invention relates to an object with a closed contour in two separable pieces (12, 112). The first piece (12) extends over a first part (C1) of the contour and is formed by two elongate elements (14, 16) which are generally parallel and separated by a gap (18) and rendered integral at their ends by linking members (20). The second piece (112) extends over a second part of the contour (C2), complementing the first part, and is formed of at least one elongate element which follows the said second part of the contour (C2) and ends in blocking members (120). This elongate element (114) is received in the gap (18) between the two elongate elements (14, 16) of the first part (12). <IMAGE>
