Abstract: The invention relates to a plate (2) with a slot (7), adjacent to at least one hole (4, 6) therein, which traverses the whole of said plate and which extends along said hole (4, 6) on a part of the perimeter of said hole (4, 6). The hole (4, 6) and slot (7) thus define a band of material (8) between them which is flexibly elastic. The band (8) comprises locking means (9) on the edge thereof defining the hole (4, 6), which project towards the interior of the hole (4, 6). The object (3), for placement in said hole (4, 6), comprises complementary locking means (10) which, when said object (3) is engaged in said hole (4, 6) come into engagement with the locking means (9) on the band of material (8) such as to connect said object (3) to the plate (2) or to fix said plate (2) to a bone.
