An assembly plug for closing openings, in particular openings in vehicle bodies and the like, wherein the assembly plug has a first device, which has structure for engaging in a latching manner behind an edge of an opening and there is also a second device, with which the structure for engaging in a latching manner behind an edge of a hole can be actuated radially outward into a latching position, wherein the second device is axially displaceable in the first device and the actuation can be carried out by the axial displacement.

A fastener includes a fastening pin and a sleeve component disposed around the fastening pin and movable up and down relative to the fastening pin. The sleeve component includes fixing claws that are able to stretch outward and retract inward. A pin of the fastening pin comprises a small-diameter rod section and an upper large-diameter rod section. When the fixing claws move relative to the pin to abut against an outer surface of the upper large-diameter rod section, the fixing claws stretch outward, and the fastener is in a locked state. When the fixing claws move to the outside of the small-diameter rod section relative to the pin, the fixing claws retract inward, and the fastener is in a release state.

A method of making an assembly is disclosed. According to the method, a curable sealant is applied to a metal surface of a first article, and the curable sealant and first article are stored under conditions to maintain the curable sealant in an at least partially uncured state. The method further includes contacting the curable sealant on the first article metal surface with an electrically conductive surface of a second article, and curing the curable sealant.

The present disclosure provides a fastener. The fastener includes an elongated body having a first end and a second end opposite the first end. The fastener also includes a head having a first surface and a second surface opposite the first surface. The first end of the elongated body is coupled to the second surface of the head, and a diameter of the head is greater than a diameter of the elongated body. The fastener also includes a sleeve positioned over at least a portion of the elongated body and the second surface of the head. The fastener also includes a plurality of textured elements positioned on an exterior surface of the sleeve adjacent the second surface of the head. One or more of the plurality of textured elements extend from the exterior surface of the sleeve to the first surface of the head.

An attachment device for attaching a component to a support component, in particular a support component of a vehicle, includes a retaining element which can be inserted into an opening of the support component and which has a latching feature for releasably latching to the opening of the support component. A locking element can be inserted into the retaining element, wherein, when the locking element is inserted into the retaining element, the latching feature of the retaining element is/are blocked so as to prevent release of the latching. The retaining element has a sealing ring for bearing in a sealing manner against the opening of the support component, which sealing ring, when inserted into the opening of the support component, bears in a sealing manner against opposite sides of the support component.

A connection assembly adapted to join a surface element to an underlying support structure while maintaining a substantially zero gap abutting relation between the surface element and the support structure. The connection assembly includes a press-in retainer with a circumferential seal having a sealing foot. The sealing foot flexes about a living hinge while maintaining continuous sliding contact with the support panel without interfering with downward movement of the retainer.

A method of making an assembly is disclosed. According to the method, a curable sealant is applied to a metal surface of a first article, and the curable sealant and first article are stored under conditions to maintain the curable sealant in an at least partially uncured state. The method further includes contacting the curable sealant on the first article metal surface with an electrically conductive surface of a second article, and curing the curable sealant.

Quarter turn clip for connecting a vehicle metal sheet plate and an expanded polypropylene vehicle panel, and quarter turn clip and expanded polypropylene vehicle panel assembly. The quarter turn clip is able to perform the sealing and pre-mounting functions despite it comprise neither a sealing ring in order to ensure the sealing function nor additional pre-mounting elements in order to pre-mount the quarter turn clip into the expanded polypropylene vehicle panel.

A fastening element (1) for insertion into an opening (50) of a part (51), in particular a vehicle body part, wherein the fastening element (1) has a head region (2), a flange region (3), which is connected to the head region (2) via a first shaft region (4), and a second shaft region (5), which continues from the flange region (3) on the side opposite the head region (2) and is formed such that, in the inserted state of the fastening element (1) in the opening (50), it extends through the opening (50), at least in certain regions, and forms a snap connection with the part (51), in particular vehicle body part, wherein at least one indicator element (6) is associated with the fastening element (1) for, in particular, acoustically and/or visually signaling an assembly state of the fastening element (1).
