Hook adapted to be easily, quickly and securely attachable on both ends of an elastic cord which is used to tie objects up is disclosed; the present hook is structured to have two symmetric round ends, i.e., the right cord-fixing end and the left hook end, with a relatively large through-hole placed on the latter and three smaller through-holes disposed on the former with one of which being cut open for ready disposition of part of the elastic cord in knotting operation, and there is also provided with a hook member projectingly extended from the left end with the concave thereof facing to the right. An elastic cord can be easily attached to the right end of the present hook by first leading one end of an elastic cord downward through one of the non-opened holes thereof, forming a loop under the right end with the cord itself going therethrough, then guiding this end reversely upward through the other non-opened hole from its bottom with the frontmost end of the cord extended long enough so that when pulling the other end of the cord can make a tight knot naturally for readily securing the present hook to the elastic cord.

A hook means for releasably attaching to at least one end of an elastic cord, said hook means comprising two symmetric round ends, a left hook end and a right cord-fixing end, wherein said right cord-fixing end is provided with first, second and third through-holes which are symmetrically located at three points in a triangular arrangement, said first through-hole being closest to said left hook end and having an open cut on the periphery thereof, and said left hook end being provided with a means, defining a large through-hole, for receiving a finger at the center thereof, and a hook member projectingly extended therefrom with the concave surface thereof facing toward to the open cut, wherein a line connecting the open cut and extending through a space between the second and third through-holes also extends through said concave surface of said hook member.
