Abstract
Members for pushing the tabs of an annular part include radial studs forming cams, there being as many of these as there are catching tabs, the cams having the same distribution as the tabs into the gaps between which they are inserted in the unlocked position, each tab being equipped with a cylindrical or cam-shaped internal bearing surface capable of bearing on one of the studs in order, by reaction, to push its external catching tooth radially outward, the annular part being connected to a turning member which has a restricted angular travel between two positions, namely an unlocked and identified rotational position of the annular part, in which position the tabs are free to flex, and a locked rotational position of the annular part, in which position the tabs are locked and pushed back by their respective studs, and locked under the rolled rim.
