A two part fastener (10) for clamping together first and second members (20, 22) that have an opening (40). The fastener (10) comprises a base (12) having a plurality of legs (80, 90) resiliently biased outwardly away from each other and insertable through the opening (40). A knob (14) connected with the base (12) is manually rotatable relative to the base to control the position of the legs (80, 90). The knob (14) has a first position of rotation relative to the base (12) in which blocking portions (80, 90) of the legs are in a blocking position to block removal of the legs through the opening (40). In a second position of rotation the knob (14) blocks inward movement of the blocking portions (88, 98) of the legs (80, 90) from the blocking position, thereby blocking removal of the fastener 10. In a third position of rotation the knob (14) holds the blocking portions (88, 98) of the legs (80, 90) inward from the blocking position, thereby enabling removal of the fastener (10).

1. A two part fastener for clamping together first and second members in an overlying relationship, said first and second members having surfaces defining an opening extending through said first and second members, said fastener comprising:a base insertable into said opening, said base having a plurality of legs resiliently biased outwardly away from each other and movable between a plurality of positions relative to said first and second members, said legs being insertable through said opening; and an actuator connected with said base and manually rotatable about an axis relative to said base to control the position of said legs of said base relative to said first and second members; said actuator having a first position of rotation relative to said base in which blocking portions of said legs are in a blocking position to block removal of said legs through said opening; said actuator having a second position of rotation relative to said base in which said actuator blocks inward movement of said blocking portions of said legs from said blocking position, thereby blocking removal of said fastener through said opening; and said actuator having a third position of rotation relative to said base in which said actuator holds said blocking portions of said legs inward from said blocking position, thereby enabling removal of said fastener from said first and second members through said opening.
