       2 . The strap connector as claimed in  claim 1  wherein the first coupling device comprises two symmetrically configured coupling members, each coupling member comprises a cavity having an axis corresponding to that of the coupling member, and the cavities are assembled together to define the first engaging portion thereof. 
   
   
       3 . The strap connector as claimed in  claim 2  wherein the first engaging portion has a cross-section substantially circular. 
   
   
       4 . The strap connector as claimed in  claim 2  wherein each coupling member comprises a protuberance extending radially outboard from the outer periphery of the coupling member, and wherein the strap connector further comprises a fastening device engaged with the protuberances so as to securely hold the two coupling members together. 
   
   
       5 . The strap connector as claimed in  claim 2  wherein the second coupling device comprises two symmetrically configured coupling members, each coupling member comprises a cavity having an axis corresponding to that of the coupling member, and the cavities are assembled together to define the first engaging portion thereof, and each coupling member further comprises a block extending radially outboard from the outer periphery of coupling member, each block includes a chamber therein, and the blocks are assembled together to define the second engaging portion along with the chambers are assembled together to define the compartment. 
   
   
       6 . The strap connector as claimed in  claim 5  wherein each coupling member of the first coupling device comprises at least one ridge extending radially and circumferentially outboard from the outer periphery thereof, wherein each coupling member of the second coupling device comprises at least one recess extending radially and circumferentially outboard from the inner periphery thereof, and wherein the at least one ridge are received in the at least one recess whereby disengagement of the first coupling device and the second coupling device is prevented. 
   
   
       7 . The strap connector as claimed in  claim 6  wherein each coupling member of the second coupling device comprises a protuberance extending radially outboard from the outer periphery of coupling member, and wherein the strap connector further comprises a fastening device engaged with the protuberances so as to securely hold the two coupling members together when second coupling device is connected to the first coupling device. 
   
   
       8 . The strap connector as claimed in  claim 7  further comprising a fastening device engaged with the blocks of so as to securely hold the two coupling members together when second coupling device is connected to the first coupling device. 
   
   
       9 . The strap connector as claimed in  claim 5  wherein each chamber comprises a first section and a second section in communication with the first section, the first section has a radius larger than that of the second section, and the first and second sections have cross sections substantially semicircular. 
   
   
       10 . The strap connector as claimed in  claim 5  wherein the chambers are assembled together to form a substantially semi-spherical compartment when the second coupling device is connected to the first coupling device. 
   
   
       11 . The strap connector as claimed as claimed in  claim 9  wherein the connecting portion of the ring shaped member comprises a first end and a second end connecting to the first end, the first end is received in the first section of each chamber, and the second end is received in the second section of each chamber. 
   
   
       12 . The strap connector as claimed as claimed in  claim 10  wherein the connecting portion of the ring shaped member is substantially spherical. 
   
   
       13 . The strap connector as claimed as claimed in  claim 1  wherein the first coupling device is connected to the second coupling device in a gapped relation. 
   
   
       14 . The strap connector as claimed as claimed in  claim 13  wherein the ring shaped member is connected to the second coupling device in a gapped relation.
