A system for securing a bone fixation device to a bone, comprising: a flexible longitudinal element, comprising a longitudinal section extending between a head at a proximal end thereof and a distal end, and configured to wrap about and stabilize a target portion of bone, the longitudinal section including a plurality of projections extending distally from a first surface thereof, each projection including a proximal abutting surface; and a locking block configured to be received within the bone fixation device and including: a channel extending therethrough sized and shaped to slidably receive therein a portion of the longitudinal element, the channel having an open first end and an open second end, wherein the first end of the channel is sized to receive a single thickness of the longitudinal element therethrough and the second end of the channel is sized to receive two thicknesses of the longitudinal element therethrough side-by-side; and a recess configured to lockingly engage the head of the longitudinal element, the longitudinal element including a tab protruding distally from the longitudinal section at a predetermined angle and separated from the head by a predetermined distance along the longitudinal section, wherein the tab is configured so that when the longitudinal section is passed from the second end of the channel, looped around a target bone and reinserted into the first end of the channel and through the channel, the tab engages one of the proximal abutting surfaces, preventing a portion of the longitudinal element on which the projections are formed from moving proximally relative to the tab. a flexible longitudinal element, comprising a longitudinal section extending between a head at a proximal end thereof and a distal end, and configured to wrap about and stabilize a target portion of bone, the longitudinal section including a plurality of projections extending distally from a first surface thereof, each projection including a proximal abutting surface; and a locking block configured to be received within the bone fixation device and including: a channel extending therethrough sized and shaped to slidably receive therein a portion of the longitudinal element, the channel having an open first end and an open second end, wherein the first end of the channel is sized to receive a single thickness of the longitudinal element therethrough and the second end of the channel is sized to receive two thicknesses of the longitudinal element therethrough side-by-side; and a recess configured to lockingly engage the head of the longitudinal element, a channel extending therethrough sized and shaped to slidably receive therein a portion of the longitudinal element, the channel having an open first end and an open second end, wherein the first end of the channel is sized to receive a single thickness of the longitudinal element therethrough and the second end of the channel is sized to receive two thicknesses of the longitudinal element therethrough side-by-side; and a recess configured to lockingly engage the head of the longitudinal element, the longitudinal element including a tab protruding distally from the longitudinal section at a predetermined angle and separated from the head by a predetermined distance along the longitudinal section, wherein the tab is configured so that when the longitudinal section is passed from the second end of the channel, looped around a target bone and reinserted into the first end of the channel and through the channel, the tab engages one of the proximal abutting surfaces, preventing a portion of the longitudinal element on which the projections are formed from moving proximally relative to the tab.
