Abstract: This technology includes a device designed to retain a cable or cable connector when connected to a receptacle. The device is composed of a base bracket that interfaces with a receptacle or receptacle housing and cable bracket that interfaces with a cable or cable connector. A tool may be required to disconnect the brackets or free the cable from the receptacle.

Abstract: A hose or cable protector has a pair of articulating guides, each with rollers for creating an arcuate hose path around the sharp corner of a tunnel mouth which would otherwise cause abrasion to the hose. A stop imposes a guide to guide angle of eighty (80) degrees but the usual angle is greater and up to one hundred and twenty (120) degrees. Arches span the guides and retain the protector on the hose or cable. In a variant, the arches are spring loaded and adjustable to retain or release the hose. A control line positions the protector at the selected site.

Abstract: The invention concerns a connection between a largely rigid pipeline and a flexible conduit element by means of a steel nipple, reaching with its one end into the pipeline and with its opposite end into the flexible conduit element, wherein the flexible conduit element is secured to the nipple by means of a clamping sleeve. The basic problem, to configure a flow-favorable connection between a rigid pipeline and a flexible conduit element so that a compact tie-in of the flexible conduit element is possible without the materials being affected by the type of connection technique, is solved in that the pipeline in the segment receiving the nipple and the clamping sleeve are subjected to magnetic pulse shaping coils to reduce a cross section thereof and the pipeline and the nipple have substantially the same inner diameter.
