Abstract: A system including a releasable connector having a housing and a split ring, and a complementary mandrel that is attachable/detachable from the connector, is provided. The mandrel is designed to be received into the housing such that a portion of the mandrel extends out of the housing for connection to a tool. The split ring is disposed in an annular space between the housing and the mandrel when the mandrel is in the housing. The split ring includes at least one set of threads and a detent formed on a radially internal surface, and the mandrel includes complementary threads. The threads on the split ring fully engage the complementary threads on the mandrel when the mandrel is in a particular axial position within the housing. The detent prevents the split ring from collapsing into engagement with the threads on the mandrel until the mandrel is in a desired axial position.
