The device (1) has a blocking element (3) comprising an elastically deformable locking tab (28) that includes a free end oriented toward a base (22). An anchoring element (2) has an upright delimiting a reception zone (38) of the tab with an expansion rod (31) in an expansion position of blocking element (3). The upright is provided with a stop (40) cooperating with the tab for locking the blocking element with respect to the anchoring element in the expansion position. The tab is inclined with respect to perpendicular to the base at an angle (alpha) ranging between 0 degrees and 30 degrees. |
