     FIELD OF THE INVENTION 
     The present invention relates generally to an electrical plug, and more particularly to an electrical plug compatible with the outlets of various specifications. 
     BACKGROUND OF THE INVENTION 
     The conventional electrical plug comprises an insulating body, two prongs projecting from one end of the insulating body, and a cord fastened to the other end of the insulating body. The two prongs are fixedly projected from the one end of the insulating body and can be therefore fitted into an outlet of certain specifications. In light of the outlet specifications being different from country to country, the conventional electrical plug is limited in its use. Such a limitation in use of the conventional electrical plug often brings about inconvenience to an international traveler. 
     BRIEF SUMMARY OF THE INVENTION 
     The primary objective of the present invention is to provide an electrical plug which is free of the shortcoming of the conventional electrical plug described above. 
     In keeping with the principle of the present invention, the foregoing objective of the present invention is attained by an electrical plug comprising two insulating bodies and two prongs which are projected respectively from one end of the insulating bodies and are connected to a bonding wire. The two insulating bodies are separably held together so as to enable the two prongs to be fitted into outlets of various specifications. 
     The features and the advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of two preferred embodiments of the present invention with reference to the accompanying drawings.

     DETAILED DESCRIPTION OF THE INVENTION 
     As shown in FIGS. 1-5, an electrical plug  10  embodied in the present invention comprises a first insulating body  11 , a second insulating body  12 , and two prongs  13  projecting respectively from one end of the two insulating bodies  11  and  12  such that the two prongs  13  are connected to a bonding wire  14  which is fastened to the other end of the two insulating bodies  11  and  12 . The two insulating bodies  11  and  12  are separably held together, as shown in FIG.  2 . The first insulating body  11  is provided with a plurality of retaining slots  11 , while the second insulating body  12  is provided with a plurality of retaining projections  121  opposite to the retaining slots  111  of the first insulating body  11 . These two insulating bodies  11  and  12  are separably held together such that the retaining projections  121  of the second insulating body  12  are separably retained in the retaining slots  111  of the first insulating body  11 . The electrical plug  10  of the present invention further comprises a first extension insulation body  21  and a second extension insulation body  22 , which are basically similar in construction to the first insulating body  11  and the second insulating body  12 , with the difference being that the prongs  23  of the two extension insulation bodies  21  and  22  are different in cross sectional profile from the prongs  13  of the two insulating bodies  11  and  12 , and that the two extension insulation bodies  21  and  22  are respectively provided with an insertion hole  212 ,  222 . 
     The first extension insulation body  21  is provided with a plurality of retaining slots  211 , while the second extension insulation body  22  provided with a plurality of retaining projections  221  opposite to the retaining slots  211  of the first extension insulation body  21 . The first extension insulation body  21  is removably joined with the first insulating body  11  in such a way that the prong  13  of the first insulating body  11  is removably inserted into the insertion hole  212  of the first extension insulation body  21 , and that the prong  13  is electrically connected to the prong  23  of the first extension insulation body  21 . Similarly, the second extension insulation body  22  is removably joined with the second insulating body  12  and is separably held together with the first extension insulation body  21  by the retaining projections  221  which are separably retained in the retaining slots  211  of the first extension insulation body  21 . 
     As shown in FIGS. 10 and 11, an electrical plug of the second preferred embodiment of the present invention comprises a first insulating body  11 , a second insulating body  12 , a grounding insulating body  41 , and prongs  13  and  40  which are respectively projected from one end of the insulating bodies  11 ,  12 , and  41 . A bonding wire  14  is fastened to the other end of the insulating bodies  11 ,  12 , and  41  and is connected with the prongs  13  and  40 . 
     The electrical plug of the second preferred embodiment of the present invention further comprises a first extension insulation body  215  a second extension insulation body  22 , and a grounding extension insulation body  44 . These three extension insulation bodies  21 ,  22 , and  44  are basically similar in construction to the three insulating bodies  11 ,  12 , and  41 , with the difference being that the prongs  13  and  40  of the three insulating bodies  11 ,  12  and  41  arc different in cross sectional profile from prongs  23  and  43  of the three extension insulation bodies  21 ,  22  and  44 , and that the three extension insulation bodies  21 ,  22  and  44  are respectively provided with an insertion hole  212 ,  222 ,  442 , which are dimensioned to accommodate respectively the prongs  13  of the first insulating body  11  and the second insulating body  22 , and the grounding prong  40  of the grounding insulating body  41 . 
     The three extension insulation bodies  21 , 22  and  44  are respectively provided with a plurality of retaining portions  211 , 221 , 441 , by which the three extension insulation bodies  21 ,  22  and  44  are separably held together as a unit, as illustrated in FIG.  11 . 
     The electrical plug of the first preferred embodiment of the present invention is compatible with two outlets  30  and  31 , as shown in FIGS. 6 and 7. The first outlet  30  is provided with two first prong slots  301  while the second outlet  31  is provided with two second prong slots  310  different in cross sectional profile from the two first prong slots  301 . 
     The electrical plug of the second preferred embodiment of the present invention is compatible with two outlets  50  and  51 , as shown in FIGS. 8 and 9. The first outlet  50  is provided with three rectangular prong slots  501 , while the second outlet  51  is provided with two rectangular prong slots  511 , and one round prong slot  512 . 
     The embodiments of the present invention described above are to be regarded in all respects as being illustrative and nonrestrictive. Accordingly, the present invention may be embodied in other specific forms without deviating from the spirit thereof. The present invention is therefore to be limited only by the scope of the following claims.
