The invention relates to a closure kit comprising two extra elements (200, 250) which can be successively engaged and separated, and a cursor (100) comprising a base (110), two lateral side plates (120, 130), a central wall (140) and a sole (142) linked to the central wall (140), characterized in that at least one of the two elements (200, 250) comprises a structure (210, 260) forming a stop for the sole (142) in order to prevent the cursor (100) from retreating as a result of the effect of a strain tending towards tearing. |
