A fastener is disclosed. The fastener includes a housing, a cage, a plurality retaining members and a plunger. The plunger is at least partially movable within said cage between a first position to cause said one or more retaining members to be displaced radially outwardly thereby mechanically coupling said housing to said cage, and a second position to allow said one or more retaining members to be displaced radially inwardly thereby allowing said housing to be uncoupled from said cage.

1. A fastener, comprising: a housing, wherein the housing forms a housing cavity, wherein the housing cavity includes at least two recesses, wherein the at least two recesses includes a first recess and a second recess that are spaced apart by an axial distance;a cage at least partially disposed in said housing cavity, wherein an outer surface of the cage is spaced apart from an inner surface of the housing that forms the housing cavity, wherein the cage defines: a cage cavity, and a plurality of passages aligned with said first recess and said second recess, wherein the plurality of passages includes a first circumferential group of passages and a second circumferential group of passages that are also spaced apart by the axial distance;a plurality of retaining members at least partially retained within said plurality of passages, wherein the plurality of retaining members includes a first group of retaining members and a second group of retaining members, wherein the first group of retaining members are disposed within the first circumferential group of passages, wherein the second group of retaining members are disposed within the second circumferential group of passages, wherein the first group of retaining members arranged within the first circumferential group of passages are aligned with the first recess for selective communication with the first recess, wherein the second group of retaining members arranged within the second circumferential group of passages are aligned with the second recess for selective communication with the second recess;a plunger including a surface that engages the plurality of retaining members, wherein the plunger is at least partially movable within said cage cavity between: a first position to cause said plurality of retaining members to be displaced radially outwardly from the first and second circumferential groups of passages of the cage to the first and second recesses of the housing thereby mechanically coupling said housing to said cage, and a second position to allow said plurality of retaining members to be displaced radially inwardly from the first and second recesses of the housing to the first and second circumferential groups of passages of the cage thereby allowing said housing to be uncoupled from said cage, wherein the plunger includes a distal end and a proximal end, wherein the plunger is at least partially disposed in said cage cavity; andan end plug including a distal end, a proximal end and an outer threaded side surface, wherein the cage cavity includes an inner threaded surface, wherein the outer threaded side surface of the end plug threadingly engages the inner threaded surface of the cage cavity. 2. The fastener according to claim 1 further comprising: an urging member including a distal end and a proximal end, wherein the proximal end of the urging member is disposed directly adjacent the distal end of the plunger, wherein the distal end of the urging member is disposed directly adjacent the proximal end of the end plug, wherein the urging member is completely contained within the cage cavity. 3. The fastener according to claim 2, wherein said side surface of the plunger includes first and second side surfaces that are spaced apart by the axial distance between the distal end of the plunger and the proximal end of the plunger, wherein each side surface includes: a first retaining member engagement surface, wherein the first retaining member engagement surface defines a first axial segment of the plunger to have a first diameter,a second retaining member engagement surface, wherein the second retaining member engagement surface defines a second axial segment of the plunger to have a second diameter, wherein the second diameter is less than the first diameter, wherein contact of a corresponding one of the first group and the second group of retaining members with the first engagement surface results in the group of retaining members being displaced radially outwardly, wherein contact of the corresponding group of retaining members with the second engagement surface permits the group of retaining members to be displaced radially inwardly. 4. The fastener according to claim 3, wherein each said side surface includes an intermediate retaining member engagement surface between the first and second retaining member engagement surfaces, wherein the intermediate retaining member engagement surface defines a third axial segment of the plunger to have a frusto-conical shape. 5. The fastener according to claim 2, wherein the plunger is completely contained within the cage cavity. 6. The fastener according to claim 2, wherein the spaced apart relationship of the outer surface of the cage and the inner surface of the housing that forms the housing cavity provides means for ensuring a consistent and repeatable connection between the cage and the housing by reducing a likelihood that contaminates located therebetween will interfere with connecting the cage and the housing of the outer surface of the cage engaging the inner surface of the housing. 7. The fastener according to claim 2, further comprising: an actuator rod attached to the plunger, wherein the actuator rod extends through a bore formed in the cage and out of the cage. 8. The fastener according to claim 2, wherein the outer surface of the cage and the inner surface of the housing are spaced between .005 inches and .500 inches. 9. The fastener according to claim 2, wherein the outer surface of the cage and the inner surface of the housing are spaced between .020 and .200 inches. 10. The fastener according to claim 2, wherein the outer surface of the cage and the inner surface of the housing are spaced between .050 and .150 inches. 11. The fastener according to claim 2, wherein the spacing between the outer surface of the cage and the inner surface of the housing ranges anywhere between .005 inches and .500 inches continuously along an axial length of cavity. 12. The fastener according to claim 11, wherein the spacing between the outer surface of the cage and the inner surface of the housing extends angularly continuously 360° . 13. The fastener according to claim 2, wherein each retaining member of each of the first and second groups of retaining members are angularly offset from one another at an angle, wherein the first group of retaining members are angularly offset from the second group of retaining members by an angle. 14. The fastener according to claim 2, wherein the housing is attached to an implement, wherein the cage is attached to a handle.
