Abstract: A fastening device includes a male member having a head portion at a proximal end along a first central axis, an impact retention stem protruding from the head portion along the first central axis towards a distal end, and a tooth portion. A female member, having a first cavity, extends along a second central axis to guidingly receive the impact retention stem, a periphery of the female member having a lip portion extending towards the second central axis and adapted to lockably engage with the tooth portion, and a second cavity, extending perpendicular to and intersecting the second central axis. A locking member is configured to be guidingly received by the second cavity and is adapted to retainingly receive the impact retention stem and provide a biasing force along the first central axis towards the head portion in cooperation with the tooth portion when operably engaged with the lip portion.

Abstract: The female attachment, which is made of plastics material, has a recess and at least two lugs projecting into the recess for clipping it to a stud. It includes connecting members extending between a first body and a second body and delimiting the recess, the connecting members comprising at least one rigid arm and at least two flexible strips separated from each other. The obturator includes a female attachment of the above kind and a skirt.

Abstract: The snapping-in foot (3) of this fastener (1) has a flat rigid web (10) and two curved flexible flanges (11A, 11B) each connected to the web (10) and having, opposite a plane face (14A) of the web, an internal surface bordered by this plane face of the web, by a longitudinal edge (16A) of this flange and by a transverse edge of this flange, with the internal surface of each flange (11A) being concave and with the longitudinal edge (16A) of each flange having, seen by an observer disposed parallel to the plane face (14A) of the web (10) opposite this internal surface, a V shape whose apex, directed outwards, is situated at the level of a change-of-direction plane (18) on each side of which the external surface of the foot (3) tapers.
