1. A fastener device for fastening an article on a support plate, which fastener device comprises: a hollow body that is for housing in an engagement opening of said support plate, and that is provided with anchor means that are suitable for securing it to said support plate; a slider that is suitable for successively being engaged in and extracted from said hollow body, and that is provided with attachment means that are suitable for securing it to said article; and blocking means that are arranged:
on application of a first longitudinal thrust on said slider, initially to allow said slider to be engaged longitudinally in said hollow body, and subsequently tending to hold said slider blocked longitudinally relative to said hollow body in a first blocking position in which it cannot be engaged longitudinally beyond said first blocking position; and on application of a first longitudinal removal force on said slider following said first longitudinal thrust, to retract in part and initially unblock said slider from said first blocking position and allow it to be removed in part from said hollow body starting from said first blocking position, and subsequently block said slider longitudinally in a second blocking position that is longitudinally offset from said first position and in which it cannot be removed from said hollow body and cannot be engaged longitudinally beyond said second blocking position; wherein said blocking means comprise both at least one side opening that passes through said hollow body and also an elastically-deformable blocking tab that is carried by said slider and that, during engagement of said slider in said hollow body, is for deploying sideways into said side opening and for bearing simultaneously beneath said support plate so as to oppose any longitudinal removal of said slider, and against said slider so as to oppose any longitudinal thrust of said slider, and thus define said first blocking position. |
