A split retaining ring for a connection assembly adapted for connecting an instrument or other device to a vessel, such as a pressure vessel. The connection assembly includes a base, an instrument or device, and a split retaining ring wherein the split retaining ring includes overlapping end portions. The split retaining ring also includes an annular rib adapted for engaging a ferrule of the instrument or device in order to substantially sealing engage the instrument or device to the base.

A radio-frequency identification (RFID) fluid connection, including a tube or hose, the tube or hose including a radially outward facing surface, a RFID assembly or label connected the radially outward facing surface, including a RFID tag, and at least one contact electrically connected to the RFID tag.

A coupling device for coupling flanges of two pipes includes a chain assembly and a positioning mechanism. The chain assembly includes plural connecting pieces pivotally connected one by one by pivot members. The connecting pieces at two opposite ends of the chain assembly are defined as a first connecting piece and a second connecting piece. A first pivot member is arranged at the free end of the first connecting piece, and a second pivot member is arranged at the free end of the second connecting piece. The positioning mechanism includes a first portion and a second portion pivotally connected. The first portion is pivotally connected to the first pivot member or the first connecting piece, and the second portion is detachably positioned to the second pivot member. The first portion is rotatable between a release position and a fixed position relative to the second portion.
