  • Patent number: 11578748
    Abstract: This fastener assembly includes a body, an elongated member and a split wedge. The body defines a cavity that converges. An access opening at a small end provides access to the cavity. The member has a circumferential external profile at one end. The split wedge has two or more wedge segments with a flexible hinge connecting each of the wedge segments. Each of the wedge segments has an internal profile. The member is inserted through the access opening into the cavity of the body, the wedge segments of the split wedge are positioned circumferentially around the member and then the split wedge is wedged in the cavity to maintain the external profile of the member engaged with the internal profile of the wedge segments of the split wedge.

  • Patent number: 6353179
    Abstract: A cable entry system includes a length of a grooved pipe adapted for extending through a bore in a wall. A further length of pipe is able to be connected to a rear portion of a socket on an inner side of the wall, with a cap having an aperture through which a cable is able to pass. An additional length of pipe is adapted to be closed by the cap on an outer side of the wall. The cap may be provided with an external circumferential tooth for snapping into a groove of the grooved pipe. In an alternative embodiment, the aperture in the cap is formed by an axially extending slot, which extends through the inner end of the cap, so that the cap may be fitted after installation of the cable.
