ABSTRACT OF THE INVENTION The invention relates to a process for producing ready-to-use slats from semifinished slat portions for a slatted Venetian blind with vertically directed slats, as well as retaining means suitable for the same. In connection with the process the slat portions are in each case cut at their free lower end to the length corresponding to the installation height, plus an extra length taking account of a wrap-over portion. The wrap-over portion of a slat is in each case wrapped over at a bending edge predetermined by the use length. The lower end part of a slat is provided in the vicinity of a wrap-over portion with a system of perforations consisting of at least two holes for receiving the retaining pins of a retaining means. The retaining pins are passed through the holes and locked. The retaining means is characterized in that the retaining pins (41) to be passed through the holes (37, 37') have a substantially cylindrical pass-through portion, (42), whose diameter (d) is substantially the same as the diameter of the holes (37, 37') and which can be locked by means of a locking means (43) and that the pass-through portion (42) is followed by a head (44) which is larger than the latter and prevents the pin from slipping through the particular hole (37 or 37') (Fig. 6).
