<p>The ring (1) has a collar (6) with a V-shaped recess extending radially in a region of a joint (9), where the ring is made of polymer. The recess has limiting surfaces forming stop surfaces to limit an opening angle of the ring. The stop surfaces form an opening angle of 90 degrees in a non-broken state of the ring. A target break point (8) extends from a front side (16) of a support surface (5) facing away from the collar. A slot-shaped break (18) is formed along circumference of the collar in a region of the break point, where the break extends from a front side (17) to the break point.</p> |
