         5 . The slider according to  claim 4 , wherein:
 the first platform has a first receiving structure and the cap has a first attaching member, wherein the first receiving structure and the first attaching member interact to attach the cap to the pulling member.   
     
     
         6 . The slider according to  claim 4 , comprising
 a first protruding block disposed on the first platform; and   a first receiving member on the cap to correspond to the first protruding block.   
     
     
         7 . The slider according to  claim 6 , comprising:
 a first sliding groove on the first platform, wherein   the first sliding groove is located between the protruding block and one of the two walls.   
     
     
         8 . The slider according to  claim 7 , comprising:
 a first sliding portion on the plate spring, wherein:   the first sliding portion is configured to slide on the sliding groove.   
     
     
         9 . The slider according to  claim 1 , wherein:
 the pulling member is integrated to the upper wing.   
     
     
         10 . The slider according to  claim 1 , wherein:
 the cap is configured not to receive a pulling force when a pulling force is exerted to the pull tab.   
     
     
         11 . The slider according to  claim 1 , wherein:
 the cap is removably attached to the pulling member.   
     
     
         12 . A process of making a slider, comprising the steps of:
 providing a slider body with an upper wing;   attaching a pulling member with two walls on the upper wing, the two walls having an aperture on each wall, wherein the two walls are longitudinally disposed on the upper wing, an assembly groove is formed between the two walls and the apertures form a transverse channel;   providing a pull tab with a pintle and disposing the pintle in the transverse channel; and   covering the assembly groove with a cap.   
     
     
         13 . The process of  claim 12 , wherein a chamber is disposed in the assembly groove and a locking opening is disposed on the upper wing, comprising the steps of:
 disposing a locking lever having a pivot end and a locking prong in the assembly groove; and   disposing a plate spring, wherein the plate spring contacts the locking lever and exert a force on the locking lever, wherein:   the locking lever is so configured that the pivot end is disposed in the chamber and the locking prong penetrates the locking opening to be disposed between two zipper teeth when the pull tab is in a resting state and the locking prong is lifted to disengage from the zipper teeth when a pull force is exerted on the pull tab.   
     
     
         14 . The process according to  claim 13 , wherein:
 a first platform is disposed close to an end of the assembly groove   
     
     
         15 . The process according to  claim 14 , wherein:
 the first platform has a first receiving structure and the cap has a first attaching member, wherein the first receiving structure and the first attaching member interact to attach the cap to the pulling member.
