The present invention provides novel high-efficiency pipe means (a top joint ring) which, when a fastening piece on one side and an operating hook lock on the other side are tightened by means of female and male screws in order for pipe connection, uses strong localized compression on portions of the circumferences of pipes on either side thereof to fix same and provides complete pipe connectivity without ever having a disengagement of the connection. In particular, the top joint ring for pipe connection of the present invention comprises: a left side tapered joint tube and a right side tapered joint tube respectively having a pipe insertion recess formed therethrough in the bore thereof and being cylindrical overall, having regions from the ends at the left sides and the right sides to the centers thereof progressively increasing in diameter towards the centers and having predetermined sloped angles, are formed symmetrical to each other; a bore joint ring formed protruding inward at the center at which the left side joint tube and the right side joint tube meet each other; and a plurality of long cutout recesses capable of assisting a contraction effect at the left and right joint tubes including the bore joint ring without stressing the bore joint ring. |
