    摘要： 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.
