Disclosed is a speaker unit which includes a provisionally fastening mechanism provided on a side surface of a cabinet section for provisionally fastening the speaker unit to a mounting part with at least a portion of the cabinet section inserted in an opening section of the mounting part from a face side of the mounting part. The provisionally fastening mechanism includes an engagement section for provisionally fastening the speaker unit to the mounting part, and a retention section for retaining the engagement section. The engagement section is movable between an engagement position in which the engagement section engages with the mounting part and a cancellation position in which the engagement section cancels the engagement with the mounting part by being moved away from the mounting part, and the retention section retains the engagement section in the cancellation position.

A retaining arrangement can secure an electronic module to a body. Two end wedges, each with a ramped end, can be mounted on a rail. At least one inner wedge can be slidably mounted on the rail between the two end wedges, with ramped ends of the at least one inner wedge engaging the ramped ends of the two end wedges. Each of the ramped ends can have a respective angle of between 20 degrees and 30 degrees. An even number of inner wedges can be provided. A pin extending through mounting holes in one of the end wedges, but not extending into the rail, can secure the end wedge to a screw for moving the retaining arrangement into the compressed configuration.

A connecting bolt has a bolt shank and a bolt head which has a radially outwardly projecting bolt projection. The bolt head has a latching projection between the bolt shank and the bolt projection on the side opposite the bolt projection.

Rock bolt (1) comprising at least an elongated body (4), one end of which comprises at least a first external conical portion (16) extending through at least one hole (12) in at least a cylindrical expandable body (5), the hole (12) over a section of the bore hole in the axial direction comprises an internally conical part (15) intended to cooperate with the elongate member outer conical portion (16). Upon relative movement of the elongate body (4) and the expandable body (5) in one direction expands the expandable body in the radial direction. The relative axial movement between the elongated body (4) and the expandable body (5) is provided by at least one tensioning device (7). The rock bolt comprises at least one wedge device (2), which in use of the rock bolt, is connected to the expandable body (5) hole (12) and at least partially inserted between a first portion (17) and at least a second part (18). The rock bolt further comprises at least one connecting means (21).

The earring device (1) includes: a shaft (2) suitable for passing through the orifice; a catch (3) hinged with the shaft, the catch being suitable for adopting an unlocked position, wherein the catch is aligned with the shaft and a plurality of locking positions (17) along the shaft, wherein the catch is arranged transversely relative to the shaft; elements (17, 31, 32, 33) for reversibly locking the catch in one of the locking positions. The device makes it possible to adapt the earring to the thickness of the ear wearing same. The device is also suitable for other parts of the body liable to be pierced for the purposes of visual appeal.

According to an embodiment, a rivet includes a first cap having a front side and a back side. The first cap includes a compressed region or a slotted region between a first edge of the first cap and a second edge of the first cap, a unique identifier on the front side of the first cap, a protruding portion extending from a central region on the back side of the first cap, a foam layer adhered to the back side of the first cap with a first layer of adhesive, and a protective film adhered to the foam layer with a second layer of adhesive.

A trim panel mounting system is provided for securing a trim panel to a substrate. That trim panel mounting system includes a push pin, a push pin holder and a trim panel. That trim panel includes at least one mounting post engaging the push pin holder and a resilient retention finger capturing the push pin between the trim panel and the push pin holder.
