A closure of indicator seal is made of the rectangular integral plate in the form of a slit-type collet where the through hole is provided for passing and holding a seal female element and in the cross-section it has a form of two similar circles, which centers are located on the closure mirror plane of fore-and-aft element connected by a jumper symmetrical towards the specified plane. The plate angles are rounded. Flanging is made around its outside perimeter. The through hole is formed with cutting edges produced by the angular inner splits and turned down inside the lobe closure. On the surface of lobes between curvilinear edge sections perpendicular to its straight-line sections the stiffening ribs are made sothat their tops are turned sideward the lobes bending. |
