ABSTRACT:
A retaining element to hold together a multipart preassembled screw connection or the like until the assembly can be further processed or assembled in a later step. The retaining element includes a ring section to be installed on a free part of the multipart connection unit so as to hold together the individual parts of that section, and a handle that extends in an outward radial direction from the ring section. Once the free part of a multipart connection unit is assembled to a mating connection unit, the ring section can be removed by applying a tensile force to the handle in an upward radial direction. The ring section may have a predetermined breaking point so that the ring section becomes severed when sufficient tensile force is applied, whereby the retaining element can be removed without difficulty.
