A channel nut includes a web, a first flange projecting from the web where the first flange has a first notch for receiving a first lip of a strut channel, and a second flange projecting from the web where the second flange has a first notch for receiving the first lip of the strut channel. The first notch of the first flange and the first notch of the second flange are arranged in a non-aligned relationship with respect to each other such that the first notch of the first flange and the first notch of the second flange form a curved first seat for the first lip of the strut channel.

A connecting device for a frame structure made of support profiles and crossbars for the arrangement of solar panels, as well as a frame structure with a connecting device, is disclosed. The connecting device has a base element, a receptacle element, and a locking device by which the receptacle element can be fixed relative to the base element on the base element. The base element has a fastening section as well as a support section with a support side facing the receptacle element. The receptacle element has a receptacle for a crossbar of the frame structure as well as an application section with an application side facing the base element. The locking device has a clamping device as well as a bearing device. An application area and at least one depression area are provided between the clamping device and the bearing device.

Connecting device for a frame structure

A profiled rail has two opposite side walls () at least one connection wall () for connecting the side walls (), first and second openings () for passing therethrough a connection element () and having, respectively, first and second opening widths (B; F; C; G) measured in a direction perpendicular to a longitudinal profile axis () of the profiled rail, with a minimal distance (A; E) between the opposite wall sections () of the side walls (), which is measured in the direction perpendicular to the longitudinal profile axis () of the profiled rail, at most corresponding to the opening width of (B; F; C; G) the first and second openings ().
