     DETAILED DESCRIPTION 
       FIG. 1  shows a perspective view of a first exemplary embodiment of a device according to the invention. The exemplary embodiment according to  FIG. 1  is made of energy-elastic plastic and has a rectangular base plate  1  in this exemplary embodiment, at which on one side a single projecting longitudinal wall  2  is integrally molded in the longitudinal direction of base plate  1  and perpendicular to base plate  1 . In this exemplary embodiment, the longitudinal wall  2  is located essentially in the center of base plate  1 . 
     Further, the device according to  FIG. 1  has a number of longitudinal wall reinforcement ribs  3 ,  4 ,  5 ,  6  that extend on one side of longitudinal wall  2  in the transverse direction of base plate  1 , essentially up to the edge of base plate  1 . In this exemplary embodiment, respectively one longitudinal wall reinforcement rib  3 ,  6  is located at opposite ends of longitudinal wall  2 , while the two other longitudinal reinforcement ribs  4 ,  5  lie offset at a respectively equal distance from the longitudinal wall reinforcement ribs  3 ,  6  at the end, in the direction of the center of longitudinal wall  2 . 
     On the side of longitudinal wall  2  that is facing away from longitudinal wall reinforcement ribs  3 ,  4 ,  5 ,  6 , the device according to the invention as per  FIG. 1  has edge walls  7 ,  8  located at the end of one longitudinal side of base plate  1  that are located at a distance in the transverse direction of base plate  1  with respect to longitudinal wall  2 . Edge walls  7 ,  8  are braced by respectively two edge wall reinforcement ribs  9 ,  10 ,  11 ,  12  located at the end, pointing away from longitudinal wall  2 , in order to increase the bending resistance of edge walls  7 ,  8 . As can be seen in the illustration according to  FIG. 1 , edge walls  7 ,  8  essentially extend over the end sections of longitudinal wall  2 , which are likewise reinforced by longitudinal wall reinforcement ribs  3 ,  4 ,  5 ,  6 . 
     It can be seen in  FIG. 1  that on the sides of longitudinal wall  2  or edge walls  7 ,  8 , in thereby formed U-shaped receiving sections between longitudinal wall reinforcement ribs  3 ,  4 ,  5 ,  6  or between edge wall reinforcement ribs  9 ,  10 ,  11 ,  12 , respectively one hold-down nose  13 ,  14 ,  15 ,  16  is designed as hold-down element that respectively has on its side facing base plate  1 , a stop side oriented parallel to base plate  1 , and on the side facing away from base plate  1 , a chamfered insertion side. 
     Finally, it can be seen in  FIG. 1  that in this exemplary embodiment, in longitudinal wall  2  between longitudinal wall reinforcement ribs  4 ,  5  that lie on the inner side in this exemplary embodiment, directly adjacent to these longitudinal wall reinforcement ribs  4 ,  5 , an attachment recess  17 ,  18  is formed respectively, which breaks through longitudinal wall  2 . 
     In the receiving sections that are positioned between the sides of longitudinal wall  2  pointing toward each other and edge walls  7 ,  8 , base plate  1  respectively has a slider recess  19 ,  20  for removal purposes, in order to eject the hold-down element ( 13 ,  14 ,  15 ,  16 ). 
       FIG. 2  shows a perspective view of the exemplary embodiment in a device according to the invention as per  FIG. 1  with two belts  21 ,  22 , that are designed with connecting bars  23  that extend at regular distances transverse to belts  21 ,  22 . At connecting bars  23 , components are or were mounted that are not shown in  FIG. 1  that are transported or have been transported with belts  21 ,  22 , which typically have a tooth structure. In manipulations of this type it is sometimes necessary to connect the ends of belts  21 ,  22  with each other. 
     To do so, in a use of the device as intended according to the invention, the ends of belts  21 ,  22  are inserted between longitudinal wall  2  and edge walls  7 ,  8  in such a way, that a connection bar  23  of a belt  21 ,  22  respectively engages with one attachment recess  17 ,  18  and belts  21 ,  22 , after being pressed between hold-down noses  13 ,  14 ,  15 ,  16 , are located between base plate  1  and the stop sides of hold-down noses  13 ,  14 ,  15 ,  16  facing base plate  1 . Thus, belts  21 ,  22  are secured against displacement in the longitudinal direction, as well as also against an unintentional movement away from base plate  1 . 
     In a perspective view,  FIG. 3  shows a second exemplary embodiment of a device according to the invention that is essentially designed, in contrast to the exemplary embodiment according to  FIG. 1  with an enlarged, approximately square base plate  1  with the same, as well as correspondingly located, but double the number of super-structural components than the exemplary embodiment according to  FIG. 1 , whereby the edge wall reinforcement ribs  9 ,  10 ,  11 ,  12  are located opposite to each other. Thereby, the exemplary embodiment according to  FIG. 3  is designed with four receiving sections formed by the two longitudinal walls  2  and the in total four edge walls  7 ,  8 . 
     Base plate  1  in the exemplary embodiment according to  FIG. 3  is also designed with a number of fastening recesses  24 ,  25 , in order to mount base plate  1 , for example, with a screw or a rivet on a carrier component—not shown in FIG.  3 —such as a belt drum for storing belts  21 ,  22 , in particular with components that are mounted on such. 
       FIG. 4  shows a perspective view of the exemplary embodiment according to  FIG. 3  with two belts  21 ,  22  that are designed according to belts  21 ,  22  as shown in  FIG. 2 , with connection bars  23 . In the configuration according to  FIG. 4 , belts  21 ,  22  are inserted between edge walls  7 ,  8  that lie at different edge sides of base plate  1  so that they extend away from the device according to the invention on one side. Corresponding to the configuration according to  FIG. 2 , respectively one connection bar  23  is located in an attachment recess  17 ,  18 , in order to retain belts  21 ,  22  in a system adjacent to base plate  1  by means of hold-down elements  13 ,  14 ,  15 ,  16 . 
       FIG. 5  shows a perspective view of the exemplary embodiment according to the invention as per  FIG. 3 , now with four belts  21 ,  22 ,  26 ,  27 , the ends of which are inserted according to the configurations as per  FIG. 2  and as per  FIG. 4 , into the four receiving sections formed by the facing sides of longitudinal walls  2  and edge wall  7 ,  8 . In this way, now two pairs of belts  21 ,  22 ,  26 ,  27 , respectively oriented parallel, can be connected with each other.
