Abstract: The ligating assembly comprises a trocar (20) and a one-piece element (10) constituted by a body (11) fittable to the end of the trocar, and by a thread (14) extending from said body and forming binding means, the body including a threading channel (16) receiving the free end (15) of the thread at one of its ends and opening out inside the trocar at its other end, the thread and the channel being provided with tightening means such as co-operating notched regions (17, 18) formed on the outside surface of the thread and on the inside surface of the threading channel, serving to hold the thread in place once it has been inserted at least partially into the channel. The assembly may also include means insertable in the trocar for grasping and pulling the free end of the thread after it has been threaded through the threading channel to project beyond the channel inside the trocar, thereby enabling the ligature to be tightened by pulling on the free end.
