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.

Buckle fastener and method of application

A swivel fitting for an electrical conduit and the like including a first fitting part including a generally cylindrical tubular section extending axially with respect to a central longitudinal axis of said first fitting part; a second fitting part having a head portion and a generally cylindrical section extending axially from said head portion and in sleeved relationship within said tubular section of said first fitting part; cooperable means on said first fitting part and said second fitting part for retaining said fitting parts in assembled relationship to each other while permitting rotation of one fitting part relative to the other fitting part about said axis, said cooperable means including a generally circumferential groove formed in said cylindrical section of said second fitting part and radially inwardly extending projection means on said tubular section of said first fitting part extending into said groove to prevent axial separation of said fitting parts; and means for exerting an axial tensioning force on said first fitting part and said second fitting part.

Swivel fitting for electrical conduit and the like

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. A circumferential groove formed on the tubular section minimizes the intrusion of liquid into the channel and facilitates drainage therefrom. The fitting parts are held in assembled relationship by a circumferential groove in the cylindrical section and cooperating radially inwardly extending projections which are formed in the tubular section of the first fitting part.
