Abstract: A snap button includes a male component and a female component which couple and uncouple as a result of effort in a main axial direction. The male component has a base from which there protrudes a rounded head, which is provided with a neck which is narrower than the head. The female component has a hollow body with an opening within which the head of the male component is introduced. Two flexible bars of a plastics material are mounted in the hollow body, the flexible bars having the ends thereof blocked. The distance between the central zones of the two flexible bars is lower than the dimension of the head of the male component so that they can be flexibly forced away from each other by a force exerted by the head of the male component and to resiliently move back towards each other when the force stops.

Abstract: A female button is in an unlocked state when a rotator takes a first position and is in a locked state when the rotator takes a second position, insertion and removal of a post of a male button being allowed in the unlocked state, and insertion and removal of the post of the male button being hindered in the locked state. Arresting part or elastic member is provided with a projection which, when the rotator rotates toward the second position, displaces the arresting part toward the rotational axis before the rotator reaches the second position and, if the displacement of the arresting part toward the rotational axis is obstructed by the post, rotational resistance of the rotator is increased.
