A clip fastener comprising: a. two hingedly opposable jaws (12, 14), both jaws (12, 14) being biased into a closed position; b. a lock bar, situated within a channel in one of the jaws and capable of transverse slidable motion therethrough; and c. a spring; characterized in that: the lock bar comprises: i. a vertical notch located off center of the lock bar; ii. a horizontal notch located off center of the lock bar on an opposite side of the vertical notch; and iii. a ridge residing within the horizontal notch such that two detents are formed by the ridge and an interior of the horizontal notch; the spring is a torsion spring with at least one arm; and the clip fastener further comprises d. a stop tab, extending from one jaw proximate the vertical notch; wherein opening and closing the jaws (12, 14) defines a path of travel for the stop tab, the lock bar residing within the path of travel and said arm of the torsion spring resides within the horizontal notch of the lock bar such that upon moving the lock bar into open and closed positions the ridge of the lock bar may be selectably located upon either side of said arm of the torsion spring thereby selectively positioning the vertical notch of the lock bar in the path of travel and allowing passage of the stop tab and associated relative pivoting movement of the jaws (12, 14) when the lock bar is in an open position. a. two hingedly opposable jaws (12, 14), both jaws (12, 14) being biased into a closed position; b. a lock bar, situated within a channel in one of the jaws and capable of transverse slidable motion therethrough; and c. a spring; characterized in that: the lock bar comprises: i. a vertical notch located off center of the lock bar; ii. a horizontal notch located off center of the lock bar on an opposite side of the vertical notch; and iii. a ridge residing within the horizontal notch such that two detents are formed by the ridge and an interior of the horizontal notch; the spring is a torsion spring with at least one arm; and the clip fastener further comprises the lock bar comprises: i. a vertical notch located off center of the lock bar; ii. a horizontal notch located off center of the lock bar on an opposite side of the vertical notch; and iii. a ridge residing within the horizontal notch such that two detents are formed by the ridge and an interior of the horizontal notch; i. a vertical notch located off center of the lock bar; ii. a horizontal notch located off center of the lock bar on an opposite side of the vertical notch; and iii. a ridge residing within the horizontal notch such that two detents are formed by the ridge and an interior of the horizontal notch; the spring is a torsion spring with at least one arm; and the clip fastener further comprises d. a stop tab, extending from one jaw proximate the vertical notch; wherein opening and closing the jaws (12, 14) defines a path of travel for the stop tab, the lock bar residing within the path of travel and said arm of the torsion spring resides within the horizontal notch of the lock bar such that upon moving the lock bar into open and closed positions the ridge of the lock bar may be selectably located upon either side of said arm of the torsion spring thereby selectively positioning the vertical notch of the lock bar in the path of travel and allowing passage of the stop tab and associated relative pivoting movement of the jaws (12, 14) when the lock bar is in an open position.
