Abstract: The invention relates to a fastener (21) for arranging a rod element (9) on a mounting channel, said fastener (21) including an engaging part (22) that can be inserted and made to engage behind edges (14) of an installation opening of the mounting channel, whereby the engaging part (22) has an opening (25) with an internal thread for the rod element, a stop plate (42) for making contact on the outside of the mounting channel having a hole (44) through which the rod element (9) passes, and flexible connection elements (32) that connect the engaging part (22) to the stop plate (42; 76; 96) at a distance from each other. Moreover, a nut element (52) that has a hole (53) with an internal thread and that serves to secure the rod element (9) to the mounting channel can be rotatably held on the stop plate (42) using a holding device (62).
