A connector for coupling medical tubing (e.g., a catheter) to an implantable medical device. The connector, in one embodiment, may include a retaining member surrounding an optional housing. The retaining member may have at least one locking finger that extends through at least one corresponding window in the housing and selectively engages a stem of the medical device to retain the end of the catheter relative thereto. Application of a compressive force applied to the retaining member may cause the locking finger(s) to withdraw from the stem and release the catheter.
