A J-hook retainer includes a rigid structural component shaped with a hooked end. A soft rubber section is applied to or molded with the rigid structural component. The J-hook retainer holds a trim fabric in place over a vehicle component frame. Advantageously, the soft rubber section minimizes free play and rattling as well as assisting in avoiding sliding and detachment in case of partial contact between the J-hook retainer and vehicle component frame.

A fastener device provided with at least one movable stud and a stationary stud, the movable stud including first magnetization means that co-operate with second magnetization means of the stationary stud. At least one magnetization means is carried by a ball joint, each magnetization means being carried by movement means that cause the magnetization means to move in translation along a longitudinal axis from an engagement position to a disengagement position in reversible manner, the magnetization means being strongly magnetically attracted to each other when they are facing and each in the engagement position and being magnetically attracted only slightly or not at all when at least one magnetization means is in the disengagement position.

A clip has a base and a rattle inhibiting elastic piece. The base has a base portion that is separated from a clip central axis. The rattle inhibiting elastic piece has a slanted portion. The slanted portion extends at an angle with respect to the base, from the rattle inhibiting elastic piece portion that is provided adjacent to the base portion in a clip axial direction, toward a clip central axis side.

A fastener device provided with at least one movable stud and a stationary stud, the movable stud including first magnetization means co-operating with second magnetization means of the stationary stud. One magnetization means is carried by a ball joint, each magnetization means being carried by movement means in order to move the first magnetization means in translation in a plane and to move the second magnetization means in translation along a longitudinal axis that is substantially orthogonal to the plane from an engagement position to a disengagement position in reversible manner, the magnetization means being strongly magnetically attracted to each other when they are facing and each in the engagement position and being magnetically attracted only slightly or not at all when at least one magnetization means is in the disengagement position.
