Secure fastener for belts

Abstract

A secure fastener includes a fastening device and a security device. The fastening device includes a base, a handle pivotally installed on the base between a slackening position and a fastening position and a latch movably installed on the handle for engagement with the base in the fastening position. A first crossbar is installed on the base so that a first belt can be attached to the first crossbar. Second and third crossbars are installed on the handle so that a second belt can be directed past the third crossbar, wound around the second crossbar and directed past the third crossbar again. The security device is installed on the base for pushing the second belt against the third crossbar in the fastening position.

1 . A secure fastener comprising: 
 a fastening device comprising a base, a handle pivotally installed on the base between a slackening position and a fastening position, a latch movably installed on the handle for engagement with the base in the fastening position, a first crossbar installed on the base so that a first belt can be attached to the first crossbar, a second crossbar installed on the handle, a third crossbar installed on the handle so that a second belt can be directed past the third crossbar, wound around the second crossbar and directed past the third crossbar again; and    a security device installed on the base for pushing the second belt against the third crossbar in the fastening position.    
   
   
       2 . The secure fastener according to  claim 1  wherein the security device comprises a pressing element installed on the base for pushing the second belt against the third crossbar.  
   
   
       3 . The secure fastener according to  claim 2  wherein the periphery of the pressing element is rough.  
   
   
       4 . The secure fastener according to  claim 2  wherein the pressing element is movably installed on the base.  
   
   
       5 . The secure fastener according to  claim 4  wherein the pressing element comprises two fins, wherein the base defines two slots in and along which the fins are movable.  
   
   
       6 . The secure fastener according to  claim 4  wherein the security device comprises an elastic element installed on the base for biasing the pressing element.  
   
   
       7 . The secure fastener according to  claim 6  wherein the elastic element comprises a concave side for contact with the pressing element.  
   
   
       8 . The secure fastener according to  claim 6  wherein the security device comprises a supporting element installed on the base for supporting the elastic element.  
   
   
       9 . The secure fastener according to  claim 8  wherein the supporting element comprises a U-shaped cross-sectional configuration for receiving the elastic element.
