The invention concerns a fastener comprising a foot and a head comprising a plate to which said foot is linked, a wedge and a shank connecting said plate to said wedge, which comprises a back-plate, a rim and flexible arms connecting said rim to said back-plate, each arm comprises a first and a second curved section, and an elbow connecting them, said first section is connected to said back-plate by a first end of said arm and said second section is connected to said rim by a second end of said arm, said back-plate and each flexible arm are configured such that the distance between the center of said back-plate and said second section increases along said second section from said elbow to said rim.

A vehicle component fastener for fastening a first component to a second component of a vehicle, including a first part having a pin socket for receiving a head of a pin of the second component, and a second part having a fastening structure for fastening of the first component. The first part and the second part are connected to each other via a preassembly locking device in a preassembly position from which axial displacement into a final assembly position can occur. The preassembly locking device is releasable by introduction of the head of the ball pin or T pin into the pin socket such that the axial displacement into the final assembly position a) can be carried out with less effort than when the head of the ball pin or T pin is not introduced into the pin socket, or b) can be carried out at all.

A fastening system has at least one holding part (7) that can be fitted to a component (1) and that on one side, has a flat carrier part (29L-35) provided with adhering or hooking elements (15) projecting on one side. The opposite side at the carrier part has at least one fastener (17). A sealing device (31; 41) is on the fastener (17).

The invention concerns a fastener comprising a head and a foot comprising a rigid core and three curved flexible wings each joining said rigid core along one side, having opposite a face of said core an inside surface bordered by a longitudinal edge and by a transverse edge, and having an outside surface respectively tapering towards a pointed end which is an opposite end to said head and towards said transverse edge, on respective opposite sides of an inflection plane, each said wing being configured to bend by elastic deformation towards said core; said core comprising a hub and three small walls extending radially from said hub, whereby said core is star-shaped in cross-section; and said inside surface of each said wing is bordered by a said respective small wall which is remotely opposite said longitudinal edge.

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 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.

A device is described for fastening a ceiling profile (8) for the transition between a wall (9) and a ceiling (10) having a holder (1), which has a wall leg (2) and two holding webs (6), which engage in longitudinal grooves (7) of the ceiling profile (8). To provide simple structural conditions, it is proposed that the holder (1) forms a plastic profile having a carrying leg (3) which protrudes downward from the wall leg (2) at an acute angle, and having a support leg (4) which connects the wall leg (2) on top to the carrying leg (3), the holding legs (6) extending transversely to the wall leg (2) protrude from the carrying leg (3), and the carrying leg (3) is extended beyond the support leg (4) to form a springy catch hook (14), which interacts with a catch stop (16) of the ceiling profile (8).
