Abstract: A female coupling member releasably interconnectable with a male coupling member to form a fluid coupling is disclosed. The male coupling member has an inlet end, and an outlet end connectable to a fluid flow line. The female coupling member includes a tubular coupling body having an inlet end for axially receiving the inlet end of the male coupling member, and an outlet end connectable to a fluid flow line. The female coupling member also includes a locking element operable between a release position where the locking element is remote from the male coupling member when received within the female coupling member. A release member moves the locking element between the release position and the locking position. The female coupling member has a fastening element which is releasably securable to the release member preventing the release member unintentionally moving to the displacement position when secured to the release member.

Abstract: A shear element (10, 30, 50, 70, 70A, 90, 90A) for a coupling (110, 112, 114, 150) that couples the ends of high-pressure pipes or high-pressure hoses. The shear element (10, 30, 50, 70, 70A, 90, 90A) includes a plurality of interconnected shear bodies (12, 32, 52, 72, 72A, 92, 92A), each shear body (12, 32, 52, 72, 72A, 92, 92A) including a discrete connector section (14, 34, 54, 74, 74A, 94, 94A) which forms a connection with an adjacent shear body (12, 32, 52, 72, 72A, 92, 92A).

Abstract: The present invention relates to a protective sheath (12), a conduit assembly (11) including a protective sheath (12), and a method of forming a protective sheath (12). The protective sheath (12) has at least two layers, including: a woven layer (13); and an elastomeric layer (14); the sheath (12) being configured to locate around a length of conduit (15).
