An indication assembly (100) is presented. The indication assembly (100) comprises indication members (110, 120) further comprising interaction features (111, 121). The indication assembly (100) comprises a locking member (130) which is movable with respect to the indication members (110, 120) between a locking position and a non-locking position. The locking member (130) comprises a locking member feature (131), wherein the indication members (110, 120) are rotatable relative to the locking member (130) around an axis (x). The indication assembly (100) is configured such that when the locking member (130) is in the non-locking position, the indication members (110, 120) are rotatable by a predetermined angle in a first rotational direction. The indication assembly (100) is configured such that when the locking member (130) is in the non-locking position and the indication members (110, 120) are rotated by the predetermined angle with respect to the locking member (130), the locking member feature (131) interacts with the interaction feature (111) such that the locking member (130) is displaced into the locking position.
