A fastening device for fastening an element to the slot of a C-profile rail with a gripping element which can be inserted through the slot into the interior of the profile rail and which can be turned in the profile rail around at least one screw-in axis in such a way that it grips behind the leg of the profile rail that delimits the slot is provided. The gripping element has at least one receptacle that runs perpendicular to the screw-in axis and that serves to secure a threaded rod.

Fastening device

A conduit hanger with at least one bracket element to receive a pipe, with a load-distribution plate that is placed into the bracket element, and with a fastening device for fastening the load-distribution plate to the bracket element. The fastening device has at least one catching element to grip the bracket element as well as a counter-bearing element, which are arranged offset on the load-distribution plate in the lengthwise direction of the plate, and between which a holding space is formed for the bracket element, and that the front of the bracket element has at least one recess that corresponds to the catching element so that the bracket element can be placed into the holding space.

Conduit hanger with a load-distribution plate

A clamp for linking a mounting rail to a flange of a beam is disclosed. The clamp includes a lower base, an upper base, a connecting web, and a T-shaped back-gripping element, which is disposed at the lower base for gripping a rail opening of the mounting rail from behind. In the upper base, a threaded hole, which corresponds to the lower T-shaped back-gripping element, is provided for a clamping screw, with which the flange and the mounting rail can be pressed against one another when the lower T-shaped element grips a rail opening of the mounting rail from behind. In the lower base, a threaded hole, which corresponds to an upper T-shaped back-gripping element, is provided for a clamping screw, with which the flange and the mounting rail can be pressed against one another when the upper T-shaped element grips a rail opening of the mounting rail from behind.
