A suture device comprises a loop member formed on one side with an aperture and an access channel extending from the aperture to an opening defined by the loop. A thread connected to loop is provided along a portion of its length with a series of tapered projections. Protuberances are provided on the loop member along the access channel between the opening and the aperture for preventing a return of the thread through the channel upon a passing of the thread through the loop and subsequently through the channel into the aperture.
