The stalk portion (4) is fixed to the connecting member (10) by passing through a cover element opening (11).The width of the cover element (5) extends beyond the release button (9b) of the buckle housing (9), preventing the accidental opening thereof if the dog steps on it, and also keeps it clean from dog fur, etc.
