Abstract
A connector for releasably securing an upper section of a tubing string to a lower section includes a tubular housing containing a retaining sleeve with a collet telescoped therein and having a plurality of spring fingers interlocked with a mating section on a tubular stinger. A shoulder on the stinger serves to engage the top of the retaining sleeve and move it into a release position when setting down on the tubing string with the lower section of the string anchored in the well. The retaining sleeve is held in this position by catch means acting between the sleeve and the housing and thereby locates a recess in the sleeve to allow the spring fingers of the collet to release from the stinger as the latter thereafter moves upwardly when pulling the upper section of the tubing string from the well.
