  • Patent number: 4866817
    Abstract: A strap fastener buckle for fastening opposing ends of an object encircling strap includes first and second bridge portions partially defining first and second tubular portions and a deformable retainer extending from the buckle intermediate first and second bridge portions. One end of the strap is initially secured to the buckle. The free end of the strap is then secured to the buckle by passing the free end through first and second tubular portions, folding the free end over second bridge portion, severing the free end at a predetermined point short of the second bridge portion, and securing the severed end between first and second bridge portions by deforming the retainer to a position overlying the severed end of the strap.

  • Patent number: 4667062
    Abstract: A swivel fitting for electrical conduit and the like comprising a first fitting part having an axially extending tubular section and a second fitting part having a generally cylindrical axially extending section disposed in sleeved relationship within the tubular section of the first fitting part and having a distal end surface engageable with a transverse shoulder formed within the interior of the tubular section of the first fitting part. The second fitting part has a head portion with a generally annular channel for receiving the distal end of the tubular section of the first fitting part. The channel is delimited by a transverse surface which is axially spaced from the transverse end face of the cylindrical section so that in any position of the fitting, rainwater and other liquid spray will be prevented from intrusion into the interior wireway formed by the fitting.
