Invention provides a self latching, object-holding fixture designed to release a held object whenever the object is turned slightly in either direction. Fixture has a shaped housing and the object to be held has a mated opening of a similar matching shape. Placing an object to be held locks the object to the fixture by spring-loaded latching action. The fixture housing covers a fixed spring holding base that is anchored by any suitable means to a support surface. Covering that fixed-position base, except for exposed spring-loaded keeper latches, is a rotatable casing having a pair of spring compression cam surfaces carried by the casing. Using a cam follower action, these cam surfaces selectively cause the spring to collapse in response to the rotation of the casing holding in either direction of casing rotation. As the object/casing is turned slightly, this cam follower/spring collapse action releasably disengages the keepers from the object being held.
