A packer assembly and its method of use are provided, the packer assembly being carried on a first conduit for use in wells exposed to corrosive injection fluids, the well being encased by a second conduit having a locking recess defined therein, such as by having first and second conduit members, the conduit members being interengaged by coupling whereby the locking recess is defined by the coupling element and between the conduit members. The assembly comprises a body member communicating to the first conduit and having a slotted configuration thereon. An inwardly flexible, outwadly urged collet assembly is exterior of the body, with control means on the collet assembly being carryable within the slotted configuration. Means on said body define a pocket for selective receipt of the collet assembly for locking the collet assembly relative to the locking recess. An elastomeric packer body means below the pocket means and carried by the body member is contourably urged into sealing relation with the second conduit subsequent to locking engagement of the collet assembly and the second conduit.
