Fastening apparatus and method for fastening components to bolts

A fastening apparatus for fastening components to bolts, comprising:

• a connecting sleeve delimiting a connecting space, wherein a bolt is capable of being received and fixed in the connecting space in order to connect the fastening apparatus to a bolt,
• a cup-shaped retaining cap delimiting a receiving space for fastening a component, wherein the connecting sleeve is arranged in the receiving space, and wherein
• the retaining cap comprises a latching device having at least one latching element, which, in a pre-assembly position, engages with a counter-latching edge of the connecting sleeve such that a displacement of the retaining cap in an axial direction away from the connecting sleeve is blocked, and wherein
• the retaining cap comprises a securing element with at least one securing tab, which, in the pre-assembly position, is arranged in a securing recess such that a displacement of the retaining cap in the axial direction towards the connecting sleeve is blocked,
• such that the retaining cap is fixed in the axial direction in the pre-assembly position and is arranged on the connecting sleeve in a loss-proof manner;
• wherein a plurality of latching edges are formed on the connecting sleeve;
• wherein the retaining cap comprises a top wall and a radially circumferential side wall, wherein, in the top wall, a z-shaped passage recess is formed, and wherein a receiving slot is formed in the connecting sleeve in the region of the top wall, such that a tool is insertable into the receiving slot via the passage opening in order to retain the connecting sleeve in a rotationally secure manner by means of the tool, so that, by a rotation of 45° about a longitudinal axis, the latching elements of the retaining cap can be brought out of engagement with the latching edges of the connecting sleeve, such that the retaining cap can be pulled off of the connecting sleeve in the axial direction.
