Abstract

An attachment device secures structural component (39) to a fastening rail (32) having a slot-like opening (34). The attachment device includes a flexural member (27) to afford better handling. The flexural member (27) is deflectable in the axial direction as well as in the radial direction. A snap-in connection of the attachment device to the fastening rail (32) is achieved by the outside contour of a radially spring deflectable region (31) of the flexural member (27) which has a dimension greater than the width of the slot-like opening (34). An elastic axially extending region (28) of the flexural member (27) provides an axial prestress between a base member (21) and a cap member (29), so that accidental detachment of the attachment device positioned in the fastening rail (32) is prevented.
