ろんきわめて僅かな故障率を見込まなければならない。BACKGROUND OF THE INVENTION Devices are already known in which two blocks are joined using two holding members. In this case, these two blocks are simultaneously connected to the sixth block using a connecting member, so that the two blocks are connected by an additional connecting member. In the known design, the retaining element has the form of a set screw. The retaining members, i.e. set screws, each have 2
It has two end portions. One end section is a screw head and the other end section has threads. The four-part part with the screw head acts on one of the blocks, and the other end part with the thread acts on the other block, so that a connection of the two blocks is established. The connecting element is configured as a connecting screw, with which the first two blocks can be tightly screwed together to the Ki3 Glock. The additional connecting element, designed as a connecting screw, holds all six blocks together, so that the retaining element loses its original role. The holding element, which is designed as a set screw, therefore only serves to hold the first two blocks together until they are connected to the sixth block by means of a connecting element to form a unit. As is usual with threaded connections, a set screw is preloaded after it has been tightened. After this preload, the tightening of the coupling screw becomes slightly weaker. If the block is exposed to vibrations, there is a risk that the set screws will first loosen and possibly become dislodged over time. Most previously known screw safety systems do not provide absolute safety. Of course, a very small failure rate must be allowed for, such as when gluing a set screw.

8 are arranged on the legs 37 and are offset from each other by, for example, 180° in the radial direction. The locking piece 38 projects from the leg portion 3T in either a radial direction or an oblique radial direction. A stopper surface 46 is formed at the end of the locking piece 38 that protrudes from the leg portion 37 . The end of the locking piece 38 having a stopper surface 46 projects from the leg 3T to such an extent that the stopper surface 46 projects radially onto the retaining opening 41 and at least partially covers the retaining surface 44 in the radial direction. There is. Instead of two locking pieces 38 as shown, the legs 37
Only one locking piece 38 or two or more locking pieces 38 may be provided. To the extent that the locking piece 38 can be compressed toward the center of the retaining member so that the end portion 25 of the retaining member 10 can pass through the retaining port 41 without damaging the retaining member 10 and the block 1. The locking piece 38 itself must be elastic, and/or the leg 37 must be elastic, and/or there must be an elastic hinge between the locking piece 38 and the leg. In order to compress the locking piece sufficiently in the radial direction so that the end portion 25 of the retaining member 10 can pass through the retaining opening 41, the locking piece 38 and the leg 3 are

締付ける。The holding element 10 ensures a secure connection of the block 1 to the block 2 and possibly another block 4 or other blocks not shown. Two blocks 1, 2 or more blocks are securely connected, e.g. at a first assembly point, and these blocks are later fitted with another or more connecting screws 12, e.g. one or more, at another location. Such a connection is often desirable when the blocks 3 are to be fixedly connected to each other and possibly also to another block 3 by means of individual connecting screws 60. In the illustrated embodiment, the connecting screws 60 connect the blocks 1, 2, 4 to each other and at the same time securely tighten them on the block 3.

．． It is important that as long as 4 is connected by the connecting screw 60, it will never fall out of the retaining opening 20.41 even during long-term vibrations of the device. Falling out of the holding element 10 from the holding opening 41 is reliably prevented in an inventively desirable manner by the support element 33 (which does not pass through the holding opening 41). However, in spite of this, the coupling screw 6
0 can be disassembled, since the retaining member 10 can also be removed from the retaining port 20 with the internal thread 22, thereby allowing the blocks 1 and 4 to be separated from the block 2. It is.
