Fasteners and related systems according to the invention include a collet body having a first part of a two part anti-rotation arrangement and a cylinder body having a second part of the two part anti-rotation arrangement wherein the collet body and the cylinder body are mateably axially translatable with respect to each other, and have the same or similar outer diameter in some embodiments or not in others. A threaded member rotationally engages the collet body and compressively contacts the cylinder body during operation of the fastener to creating a clamping effect. Rotational interference between the first and second parts of the anti-rotation arrangement preferably occurs at sectional face portions of at least the collet body. Resistance to induced rotation of the cylinder body relative to a work piece rotation of the threaded member is preferably provided by a tool engaging a tool interface present on the cylinder body.

A clip includes a male member including a head portion and a shaft portion; a female member including a locking leg portion forming an insertion hole into which the shaft portion is inserted, and a flange portion provided in an upper periphery of the locking leg portion; and an engagement device restraining the head portion in the flange portion substantially at the same time when the locking leg portion comes to a use state by pushing the shaft portion into the insertion hole. Essential parts are the engagement device formed by a claw portion provided in one of the head portion and the flange portion, and a hole portion provided in the other of the head portion and the flange portion, and engaging the claw portion. The claw portion projects to a piece portion elastically moveable, and one portion of a hole forming portion dividing the hole portion is formed to be elastically moveable through the hole portion.

A fastener assembly of the present disclosure includes a grommet including a head having a through-hole formed therein and at least one leg extending downward from the head; and a pin configured with a head and a shaft inserted into the grommet. The grommet and the pin are integrally formed by a connection tip.

Expandable collet bodies with sectional finger-based anti-rotation features are disclosed. The collet body comprises not only a plurality of gripping finger as a first part of a two-part anti-rotation means (ARM), but also a first part of a two part translation arresting means (TAM), which may or may not be sectional in nature. The TAM prevents over translation of a collet body within the work piece(s), and cooperates with a second part of the TAM associated with a work piece or an auxiliary structure. In this manner, a collet body inserted into a work piece or auxiliary structure will not accidentally be pushed beyond the blind side of the work piece(s) during insertion or initial clamp-up.

The clip includes a head part, a shaft part, a pin having first and second engaged parts at the shaft part, and a grommet having a flange part with an insertion hole, a leg part, and an engaging part engaging with/disengaging from the engaged part. The pin has the engaging part near the inner periphery of the insertion hole of the flange part. The pin has guide grooves between the first and second engaged parts to guide the movement of the pin while movably engaging the engaging part. Switching between a temporary fixing state and a permanent fixing state is conducted through movement of the shaft part associated with guiding by the guide grooves. When the pin in the permanent fixing state is rotated and moved in the pull-up direction associated with guiding by the guide grooves, engagement between the engaging part and the second engaged part is released.

An interchangeable fastener system for use in combination with a perforated board or other surface on a vertical plane includes a main fastener including a base for supporting the main fastener on the perforated board; the base surrounding a channel defined by an inner surface including opposing ramp surfaces to facilitate tightening of an attachment member, and a mechanical stop adjacent each ramp surface to prevent over rotation of the attachment member; and the attachment member including an elongate member having opposing ends, wherein the elongate member is sized and configured for selective passage through the channel from the front surface through the rear surface and wherein the attachment member may be selectively rotated so that opposing ends of the elongate member are each in engaged abutment against a corresponding one of the opposing ramp surfaces and mechanical stops.

This fastening system (89), comprises a bushing (27), comprising a main body (33), having an essentially cylindrical shape which defines a main axis (X27) of said bushing, an external collar (39), provided at a proximal axial end (37) of the main body (33), a bore (49), provided through the external collar and the main body, along the main axis, and at least one clamping wing (53), which is provided within a lateral aperture (55) of the main body and is elastically orientable between an outward orientation and an inward orientation relative to the main body, the fastening system comprising a plug (29), which is shaped to be inserted, at least partially, into the bore along the main axis through the external collar, wherein the plug (29) is shaped to force the clamping wing (53) into the outward orientation when said plug is inserted in the bore (49).

A device for reinforcing, sealing or insulating a structural element in a motor vehicle includes a support having a clip for pre-fixing the device in the structural element. The clip includes a base and two flexible wings arranged on the base. The device furthermore includes an adhesive for adhesively bonding the support in the structural element. The device furthermore includes an insertion element, which can be inserted in such a way into an interspace between the base and the wings of the clip when the device is pre-fixed on the structural element by the clip that the flexible wings are restricted in their freedom of movement.

A protecting system for containing a biopharmaceutical fluid includes: a flexible pouch designed to contain a biopharmaceutical fluid; a protecting package including: two frames which respectively form a lower frame and an upper frame and which have a peripheral area; a fastening system able to clamp the two frames of the protecting package to each other, the frames sandwiching the flexible pouch. The fastening system includes at least an assembly only including: a snap including a backing part; and a cap including a washer. The lower and the upper frames of the protecting package are directly clamped between the washer of the cap and the backing part of the snap in a clamping position.

An attachment is configured to connect a first connecting plate of a vehicle component to a second connecting plate of a vehicle body. The attachment includes a body, first, second and third flanges, and a press-fit insert. The attachment is of an elastically deformable material and is configured to be inserted into first and second through holes of the first and second connecting plates. The flanges engage the connecting plates when the attachment is inserted into the through holes. The body includes a hole extending longitudinally within the body to accommodate the press-fit insert. The press-fit insert has a diameter greater than the diameter of the hole to form a snug connection between the press-fit insert and the hole. The insertion of the press-fit insert into the hole elastically deforms the attachment to urge the body radially against the connecting plates to provide a robust connection between the connecting plates.
