Abstract: A connector, typically used for connecting cables or other conduits under water. The connector has a first portion (5) which has a bayonet (15) and a second portion (25), which receives the bayonet (15). The bayonet (15) rotates in order to align the head of the bayonet (15) with a receptacle (35) in the other portion, and to jam the head of the bayonet into the receptacle in certain configurations, so that the two connector portions (5, 25) are locked together. Means are optionally provided to release the bayonet (15) from the receptacle (35) if the screw threads jam.

Abstract: A hollow monofilament of a high temperature spinnable thermoplastic such as Polyetheretherketone (PEEK) which is substantially hollow by up to about 80% by volume and has an outer diameter in the range from about 0.07 to 0.80 mm. is used in the construction of braiding in substitution for solid monofilaments with the advantage of lower cost and increased abrasion resistance.
