A channel-forming side wall (23) of the clamping element (20) and a channel-forming side wall (22) of the recess (17) form a channel (24), of which at least the upper part, in the start position of the sliding elements (14, 15), is accessible for joining elements (33) via the opening (7) in the housing (2). The sliding elements (14, 15) can be operatively connected to an actuator, such as a linear drive (12), so that the sliding elements (14, 15) can be moved by a linear movement of the linear drive (12) in a relative movement to the housing (2) from their start position into their end positions, in which the channel (24) is positioned above the outlet (9), wherein a joining element (33) is movable through the channel (24) into the outlet (9).

A pressure equalization device (1) for attachment to an opening of a housing is provided, comprising a base body (2) that includes an inlet (3) and an outlet (4), wherein the inlet (3) is designed to be fluidically connected to an interior of the housing and the outlet (4) is designed to be fluidically connected to an environment of the housing. The inlet and outlet (3, 4) are fluidically connected via a plurality of fluid channels (10, 12) extending in the base body (2). In addition, the pressure equalization device (1) comprises a gas-permeable and oil-repellent filter element (13) provided in the outlet (4), wherein a cap (17) is attached to the inlet (3), which cap (17) comprises at least one aperture (21) for the flow of a fluid.

A self-piercing rivet (1) for producing a joint has a rectangular or trapezoidal basic shape and comprises a rivet head (2) and a rivet shaft (3). The rivet shaft (3) consists of two shaft legs (4) which are spaced apart and project vertically from the rivet head (2) in one direction. The rivet head (2) and the shaft legs (4) delimit a recess (7), the opening (8) of which opens into the side opposite the rivet head (2). The shaft legs (4) taper in width from the rivet head (2) towards their shaft leg bases (9), but remain constant in height, wherein the shaft leg bases (9) each have a wedge-shaped end (23) arranged on the outside near the side surfaces (5) or near the recess. The shaft legs (4) are adapted to spread inwards or outwards during joining.

A device (1) for attaching a component to a structural component, comprising a fastening element (2) for fastening the device (1) to the structural component and a holding element (3) for holding the component. The fastening element (2) comprises a base body (4) that defines a cavity (9) which is accessible from at least one insertion opening (10) provided in a bottom side of the base body (4). Furthermore, the fastening element (2) comprises at least one fastening part (12) that projects inwardly from the base body (4) into the cavity (9). The holding element (3) is arranged on a first side wall (5) of the base body (4). The underside of the base body (4) forms a contact surface (17) for contact with the structural component, which, when viewed in the longitudinal section of the fastening element (2), runs from the first side wall (5) to a second side wall (6) opposite the first, corresponding to an involute.

A fastening element (1) for fastening a first vehicle body component (20) to a second vehicle body component (23) is provided with a base body (2) comprising a plate-shaped head part (3) with latching hooks (6) projecting in the direction of the head part (3) for latching to the first vehicle body component (20). Furthermore, the base body (2) comprises a sleeve (4) which is located centrally in the base body (2) and which comprises a first opening (8) for the receptacle of a stud (22) present on the second vehicle body component (23) and a second opening (9) for the introduction of a locking element (14). The fastening element (2) also has locking fingers (11) which project into the sleeve (4), are designed to be radially resilient and are intended for a form-fitting connection to the stud (22) that can be accommodated in the sleeve (4). The locking element (14) can be brought, by an axial movement relative to the sleeve (4) in the direction of the first opening (8), into a first locking position, in which it is held in the sleeve (4) in a form-fitting manner, whereby locking arms (16) extending axially to the longitudinal axis of the sleeve (4) in the direction of the first opening (8) are present on the locking element (14) at a distance from the locking fingers (11). The locking element (14) can be moved by a further axial movement relative to the sleeve (4) into a second locking position, in which it is held in the sleeve (4) in an interlocking manner and the locking arms (16) are in active contact with the locking fingers (11), so that the locking fingers (11) can be clamped between the stud (22) and the locking arms (16).

A fastening element (1) for reversible connection to a stud (11), comprises a base body (2) which forms in its interior a receptacle (10) defining a longitudinal axis for at least part of the stud (11). The fastening element (1) further comprising locking fingers (15a, 15b) which are mounted on the base and whose radially elastically designed free ends project into the receptacle (10), with a locking contour at the free end of the locking fingers (15a, 15b) for locking with a locking contour of the insertable stud (11). The stud (11) can be moved into a locking position in an axial direction with respect to the longitudinal axis through an input opening (13) arranged in the bottom (8) of the base body (2) and out of the locking position in a radial direction with respect to the longitudinal axis through an exit opening (14) in a first sidewall (6) of the base body (2). The free ends of the locking fingers (15a, 15b) run along a locking-finger axis and each having an end that is close to the exit opening (14) and an end that is close to a second sidewall (4) opposite the exit opening (14), wherein the distance between the ends of the locking fingers (15a, 15b) that are close to the exit opening (14) is smaller than the distance between the ends of the locking fingers (15a, 15b) that are close to the second sidewall (4).
