Zusammenfassung:	A sleeve for the centering of fasteners when installing structural parts on substructure of a building envelope is designed substantially as a hollow cylindrical sleeve body or split hollow cylindrical sleeve body. It has at least two gutter-like shell elements each having a head end and a rear end. The shell elements are grouped symmetrically about a central axis A and span between them a middle space with inner surfaces facing each other. The shell elements are spaced apart from each other and separated by axially parallel longitudinal slots, except for a connecting joint section at the head end. These sleeves are placed on a fastener and allow a precise centering in the predrilled hole of a facade plate, for example. The sleeve remains in the predrilled hole until such time as the centering of the fastener has been accomplished and is then ejected safely by driving the fastener home.
