Embodiments disclosed herein provide a device for securing a ligature to an osseous structure, the device comprising a first part, a second part, a flexible elongate member for engaging the osseous structure, a closure element, and a deformable element between the first and second parts for holding open a gap G between them. The flexible elongate member is threaded through an orifice in the first part and the gap G. The closure element is configured for clamping the first and second parts against each other, overcoming the resilience of the deformable element, so as to frictionally lock the flexible elongate member threaded through the gap G. Embodiments disclosed herein also provide a method for using the device.
