In one embodiment of the invention, there is provided a tubular assembly having a lateral connection. The assembly comprises a spool body, a carrier ring, penetrators, and an urging means. The carrier ring is built to carry the radial penetrator(s) for the carrier body. The carrier ring is mounted in sliding relationship, concentric with the carrier body. The ring is spring loaded down relative to the carrier body, against a stop shoulder (device) there. This fixes or at least stabilizes the ring on the body during running into the spool body or retrieving from the spool body. The carrier ring fits into the spool body and seats on a stop in the spool body. The carrier body also seats in the spool body, but on a different stop. Radially extending penetrators are mounted in radial ports or passages in the carrier ring, and are fixed to control fluid lines which conduct the fluid down into the well. The penetrators can move radially relative to the ring, but not axially. The urging means includes a wedge which is also mounted in the ring, one wedge for each penetrator, a carrier for the ring, and a detent mechanism which establishes cooperation between the penetrator and the carrier. The wedge(s) can move axially relative to the ring, but not radially. Finally, the wedge devices are "fixed" to the carrier body by a flexible spring detent (or similar). This arrangement links the wedge in downward movement to the carrier body, as the carrier body moves downward in turn relative to the carrier ring (and penetrators).
