Retaining device for buttons, of the type comprising a hollow body with two holes of different diameter communicating with each other by a neck of smaller width, in the smallest of which the head of a stem of the button can be retained, preceded by an annular throat that passes under pressure through the neck communicating the two holes, characterized essentially by the fact that inside the body is housed a spring comprising two branches that tend to approach by an area opposite the described neck and next to the hole of smaller diameter, so that the throat of the vagus must overcome the elasticity of the elastic piece so that it can penetrate into the hole of smaller diameter.
