ABSTRACT:
A split protective bushing is provided herein in two embodiments. According to the first embodiment, a first half ring is formed with dovetail protrusions on each end and a second half ring is formed with mating dovetail sockets on each end. Interlocking the dovetail protrusions and the dovetail sockets forms a circular bushing. According to the second embodiment, a first segment and a second segment are pivotally connected at one end of each. A second end of each segment has a tongue and latch respectively for being locked together to form a complete ring. Both embodiments include an internal thread and a lip for engaging a connector in an electric installation.
