Abstract
Abstract A pipe fitting for encompassing a conduit comprising a pair of interlocking segments with each segment comprising an arcuate configuration having at least two longitudinal edges with one edge of each segment comprising a tongue split longitudinally thereof in a direction substantially perpendicular to its length. The other of the edges comprising a groove conforming to and receiving the tongue formed on the juxtapositioned edge of the other of the segments. The tongue when forced into the opening in the groove in the other of the segments causing its two parts to engage each other along the length of the slot and when in the groove to again separate causing the tongue to interlock with the periphery of the groove thereby interlocking the segments of the pipe fitting together.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
153 words
A longitudinally divided plastic pipe fitting for encompassing conduits comprising: a pair of substantially similar interlocking plastic segments, each of said segments comprising a generally arcuate shaped body having at least two longitudinal edges, one of said edges comprising a tongue split longitudinally thereof in a direction substantially perpendicular to its length into two interconnected parts separated by a triangular slot the other of said edges comprises a groove conforming to and receiving the tongue formed on the juxtapositioned edge of the other of said segments, said tongue when forced into the opening in said groove in the other of said segments causing its two parts to engage each other along the length of its slot and when fully in the groove opening under memory of the plastic of said parts to form again said triangular slot causing the tongue to interlock with the periphery of said groove thereby interlocking the segments together.
Claim 2
Dependent Claim
153 words
