ABSTRACT:
A securing bolt device is inserted into a bore of a subassembly body. The device has a bolt and a spring element. The bolt has a shank which is insertable into the bore. A radial transverse bore extends through an end portion of the shank opposite to the insertable portion of the shank, and the shank has a blind bore in an axially directed end face. The spring element includes a loop, a first end of which is insertable into the transverse bore and a second end which is insertable into the end face bore. The loop forms a crossmember which extends across the shank of the bolt, and pressed against the bolt element by the spring force of the spring element. The locking device includes a subassembly body having a bore in which the bolt is axially movable. In a locked state a free end of the shank extends out of the bore and locks the securing bolt.
