Abstract: A new capture device comprising a plurality of axially extending tangs (42) on one (10) of a pair of complementary fittings (10, 14) in a fluid coupling and a polygonal circumferential groove (20) on the other fitting (14) adapted to engage the tangs. Upon rotational engagement of the fittings the tangs (42) engage the polygonal groove (20) and "ratchet" about the junctures between the flats (22) until the coupling is tight. Although not limited to particular materials, the new capture device is particularly suited to very tough, strong and hard materials such as titanium, stainless steel and Inconel alloy because the effectiveness of the capture device is dependent upon the stiffness of the tangs (42). The new device prevents vibrational disassembly of the complementary fittings without preventing disassembly solely with wrenches. Moreover, the complementary fittings and capture device can be repeatedly assembled and disassembled without any damage to the threads (12) or capture device.

Abstract: A push-fit connector for joining a fluid line to a pipe. The pipe has a retaining rib, and the push-fit connector has an angled pipe section. One end section of the angled pipe section can be connected to the fluid line and the other end section can be fitted to the pipe in only one relative rotational position by using a pair of retaining arms which can engage with the retaining rib when the pipe and pipe section are fitted together. To join the pipe section and the pipe together in a torsion-resistant manner at different relative rotational positions, the pipe section is fitted in a locking manner to a coupling ring. The coupling ring has retaining arms to connect one coupling ring, together with the pipe section, to the pipe. The coupling ring and the pipe section are protected from relative rotation with respect to each other by teeth which can be mutually engaged at different rotational positions of the pipe section and coupling ring.
