Such a safety clamp is the subject of the earlier patent application F 23 29 922.1-12 by the user. This fuse is bent up from a "U-shaped Bleohstan part, which is connected to a sheet metal strip running parallel to the web". The ends of the Bleohstrelfen are then rolled up or bent, and this is then bent at right angles along its connecting line with the web. To read analogously ^! the high-edged legs of the Bleohstrelfen to form the resilient legs of the vision organ bent onto the legs of the barrier device. The manufacture of this fuse is expensive because of the bending work required. Furthermore, the securing is relatively high because of the upright legs of the sloping organ, so that a relatively large amount of space is required for its assembly.

Bai de "lsi Fig. 1 geaeigtan Aasfükrungsbelsplel is with N" in the machine part, in which the axially extending machine element, ι. B. ain Bolsen B, is attached. The Bolsen B is provided with a circumferential groove into which the "two legs 2 of the" locking member 3 for securing intervene astride. At the upper end, the blocking element 3 is connected to the sloping element, consisting of the two legs S ₉ , by means of a swel spring bow 4. The two legs 5, which can rebound radially and axially, have a flat profile and are arranged at a distance from one another in a plane below the O-shaped locking member 3, 2, which is approximately parallel in the soaped Ausftthnragsbeiapiel. The distance between the two legs 5 from one another roughly corresponds to the outer diameter of the bolt or machine element B to be secured, and the two legs S run in approximately the same direction as the two legs 2 of the locking member 3.

Swlsohen the two Fedeirbogmn 4 1st on the locking member 3 in the axial direction outwardly bent flaps β are attached, the sum Assemble and decant the fuse by means of a dafttr suitable Werkseuges serves.

In this position of the safety device, the cams 7 of the legs are the locking element 3 and the cams 8 of the safety element 5 behind the shaft groove 1 bsw. de «Ausendurohaeseer of the Bolsen B and keep the safety in,, their locking division against unintentional stripping from the BoI-sen fixed.
