         16 . A connection comprising an end plate, a connecting plate, and a conical pin, wherein:
 the end plate comprises a slot connecting with a close fit to a protrusion of the connecting plate;   the protrusion of the connecting plate comprises a cut-out;   the cut-out comprises a connecting element configured to connect the connecting plate to the end plate by the conical pin; and   the connecting element comprises an opening configured to permit a lateral movement of the connecting element opposite the connecting plate when the conical pin is inserted.   
     
     
         17 . The connection according to  claim 16 , wherein the lateral movement of the opening of the connecting element of the connecting plate opposite the connecting plate is limited by a shape of the cut-out. 
     
     
         18 . The connection according to  claim 16 , wherein the connecting element of the connecting plate is resiliently suspended. 
     
     
         19 . The connection according to  claim 18 , wherein the connecting element of the connecting plate is connected to the connecting plate by retaining a thin strip of material in the cut-out. 
     
     
         20 . The connection according to  claim 17 , wherein the cut-out is funnel-shaped. 
     
     
         21 . The connection according to  claim 16 , wherein the connecting plate comprises multiple protrusions. 
     
     
         22 . The connection according to  claim 16 , wherein the connecting plate comprises a slit configured to insert a second connecting plate. 
     
     
         23 . The connection according to  claim 22 , wherein the slit of the connecting plate is connected with a close fit to the second connecting plate. 
     
     
         24 . The connection according to  claim 22 , wherein the slit of the connecting plate has a depth to the center line of the connecting plate. 
     
     
         25 . The connection according to  claim 19 , wherein the connecting element of the connecting plate is configured to move transversally opposite the connecting plate by bending the thin strip of material. 
     
     
         26 . The connection according to  claim 16 , wherein the end plate has a square shape. 
     
     
         27 . The connection according to  claim 16 , wherein the end plate includes a screw hole. 
     
     
         28 . A method for making the connection according to  claim 16 , the method comprising:
 inserting a protrusion of the connecting plate into a slot of the end plate; and   inserting a conical pin into an opening of the connecting element of the connecting plate to create the connection by permitting a lateral movement of the connecting element opposite the connecting plate.   
     
     
         29 . The method according to  claim 28 , further comprising joining the end plate and the connecting plate together using slits. 
     
     
         30 . The method according to  claim 28 , wherein the end plate is configured to connect to a beam by a screw hole.
