1. Apparatus for detachably interconnecting two objects including, in combination:
- a female structure adapted to be secured to one of the objects and defining a receptacle and an entrance leading into the receptacle, a male structure adapted to be secured to the other object and including a shank with an axis and an enlarged head on said shank adapted for movement into and out of said receptacle through said entrance and rotatable about said axis while in said receptacle, and a flexible resilient retaining member integral with said female structure and laterally offset to one side of the entrance in a first direction and normally disposed in a locking position projecting into said entrance in a second direction substantially normal to said first direction for interference with passage of said head therethrough, said retaining member being yieldably movable to a release position accommodating passage of said head through said entrance, said head being laterally truncated at one side of said axis so that while passing through said entrance in one rotational orientation thereof said head will clear said retaining member in its locking position and in all other rotational orientations it will engage said retaining member in its locking position, said retaining member being yieldably movable to its release position in response to engagement by said head during passage thereof into said receptacle and receptacle and being non-yieldably engageable by said head in said receptacle to prevent removal thereof from said receptacle in all but said one rotational orientation.

Abstract
A quick-release connecting apparatus for detachably interconnecting two objects includes male and female structures respectively attachable to the objects. The female structure has a generally U-shaped receptacle formed therein which opens at a peripheral edge thereof, the male structure has a stud projecting therefrom with a part-circular head at its distal end with a straight side which is dimensioned to be received in the receptacle from its open end and being rotatable about the axis of the stud while disposed in the receptacle. A retaining prong is unitary with the female structure and is flexibly and resiliently movable between a locking position projecting into the entrance of the receptacle and a release position out of the entrance. The stud head moves the retaining member out of the way upon insertion into the receptacle to permit insertion in any orientation, but the retaining prong prevents removal of the head from the receptacle except when it is in a single orientation wherein the straight side faces the pawl. A flexible, resilient bias finger integral with the female structure projects into the receptacle for resilient engagement with the head to inhibit rotation thereof while in the receptacle.

- a female structure adapted to be secured to one of the objects and defining a receptacle and an entrance leading into the receptacle, a male structure adapted to be secured to the other object and including a shank with an axis and an enlarged head on said shank adapted for movement into and out of said receptacle through said entrance and rotatable about said axis while in said receptacle, a flexible resilient retaining member integral with said female structure and normally disposed in a locking position projecting into said entrance for interference with passage of said head therethrough, said retaining member being yieldably movable to a release position accommodating passage of said head through said entrance, said head being non-symmetrical with respect to said axis so that while passing through said entrance in one rotational orientation thereof said head will clear said retaining member in its locking position and in all other rotational orientations it will engage said retaining member in its locking position, said retaining member being yieldably movable to its release position in response to engagement by said head during passage thereof into said receptacle and being non-yieldably engageable by said head in said receptacle to prevent removal thereof from said receptacle in all but said one rotational orientation, and bias means resiliently engageable with said head in said receptacle for frictionally inhibiting rotation of said head about said axis.
