The invention relates to a closure cap (2) which interacts with a bottle receptacle (3), whereby a locking protuberance (4) is provided on the bottle receptacle (3) and a locking arm (5), comprising an interlocking protuberance which interacts with the locking protuberance (4), is provided on the closure cap (1). In order to save a maximum amount of material while still guaranteeing reliable lockability, the interlocking protuberance (12) is arranged on a peripherally surrounding ring (5) which has, in a peripheral direction, enough length (L) to cover the locking protuberance with an elastic recoil.
