A device includes a body defining a tapered hole for guiding a member, such as a suture thread, into a tube, and a slot communicating with the hole for separating the body and the member. The body defines a bore for receiving the tube. The bore communicates with the tapered hole. The bore has a constant diameter or is tapered. A width of the bore is greater than a width of a narrowest portion of the tapered hole. The slot extends from the tapered hole and the bore to an external surface of the body. A method includes coupling a body to an end of a tube, guiding a member into the tube through a tapered hole, and separating the body and the member by passing the member through a slot.
