A fitting includes a body having at least two portions coupled together to form a body having a passage through the body. The passage allows at least a portion of a conduit to be located at least substantially lengthwise within the body. First and second ports are located on the body and are in fluid communication with the passage. A first seal is located on the passage wall between a first end of the body and the first port. A second seal is located on the passage wall between the first port and the second port. A translatable ring is located on the passage wall between the first and second seals. The ring moves along the passage wall when the first seal is activated so that the second seal is activated. The ring includes an opening proximate the first port to provide access to the conduit from the first port. The first and second seals provide a seal in the passage.

There is disclosed a clamp useful for connecting a tie-in line transversely to a carrier pipe, comprising: a lower body portion and a upper body portion that when connected together define a tubular bore, the lower and upper body portions being adapted to clamp onto the carrier pipe; a set of gripping collets positioned with the tubular sleeve bore proximate opposed ends of the upper and the lower body portions to engage such a carrier pipe; a branch tap positioned between the gripping collets and extending from one of the body portions transversely to the tubular bore; a first seal and a second seal for providing a seal between the carrier pipe and the upper and the lower body portions, the first and second seal positioned within the transverse bore and between the gripping collets and the branch tap; and a set of axial seals to form axially extending seals between the upper and lower body portions during use and to connect the first and second seals during use. The connector is particularly useful to attach branch pipes to oil or gas carrier pipes submersed undersea.
