Abstract: A fastener device for fastening an article on a support plate, and the resulting assembly, which fastener device comprises: a hollow body that is secured to the support plate; a slider that is secured to the article and that is suitable for being engaged in the hollow body; and blocking means. The blocking means comprise both at least one side opening that passes through the hollow body and also an elastically-deformable blocking tab that is carried by the slider and that, during engagement of the slider in the hollow body, is for deploying sideways into the side opening and for bearing simultaneously beneath the support plate so as to oppose any longitudinal removal of the slider, and against the slider so as to oppose any longitudinal thrust of the slider, and thus define a first blocking position.

Abstract: The invention relates to a connector for hollow portions of profile member(s), comprising two bars connected by a contact pad and intended to be inserted into the free ends of the hollow portions of profile member(s), each bar being provided with anchoring blades arranged so as to engage with the profile member(s) so as to mechanically attach the latter to the connector, and sealing blades arranged so as to engage with the profile member(s) in order to form a damp-proof course in the profile member(s). The invention also relates to a double-pane window, the frame of which consists of hollow portions of profile member(s) connected together by such a connector.

Abstract: A push nut comprises legs (6, 7), each of which is configured with outer struts (5), inner struts (17) spacedly disposed between the outer struts (5), and a tongue (19) lying between the inner struts (17) and projecting into an inner space (16) and intended to bear against a shank of a bolt that can be screwed into a thread portion (4). A high pull-out strength is thereby obtained with relatively low material expenditure.
