1. A fixation mechanism for limiting relative movement between two adjacent objects, the fixation mechanism comprising:
an elongated tie having a free end and a joined end, the tie having a smooth outer surface with no external teeth; and
a clasp coupled to the joined end of the tie, the clasp comprising:
a housing having an insertion channel in which the free end of the tie is inserted and an exit channel through which the tie exits, wherein the insertion channel and the exit channel have smooth walls with no locking teeth;
a locking mechanism positioned in the housing, the locking mechanism including a locking tine configured to permit the tie to pass through the insertion channel and out the exit channel but to prevent the tie from moving rearwardly from the exit channel to the entry channel, the locking tine having a fixed proximal end and an opposite moveable distal end that contacts the tie, the locking mechanism further comprising a generally circular plate with a central aperture that is contiguous with the insertion channel, wherein the fixed proximal end of the locking tine is joined to the plate and the distal end of the locking tine extends into the aperture; and
a stop that limits movement of the locking tine as the tie is threaded through the insertion channel and the exit channel, the stop contacts a portion of the locking tine between the fixed proximal end and the moveable distal end but does not contact the moveable distal end.
