Abstract: A plastics retaining clip for clamping e.g. brake lines to a stay bolt of a motor vehicle of the kind disclosed in German DE-OS 32 38 345 characterized by projections which protrude into the bore for housing the stay bolt, the number of the projections corresponding with the number of gripping jaws, the projections and the gripping jaws having the same angular disposition with reference to the center axis of the bore, the width of the projections being at least equal to the width of the relevant gripping jaws, and the projections at their edge which butts against the stay bolt and points in the direction of underside of the retaining clip, are formed with sharp edges. Thus when the clip is mounted on a bolt treated with underseal material, the sharp edges remove a modicum of underseal material from the stud which enables the clip to be seated securely on the stud.
