Abstract
Abstract Conduit includes coupling having a cylindrical longitudinallysplit outer member with a cylindrical opening therein and with a circular enlargement in the opening to receive a protrusion on an inner member eccentrically mounted in the outer member, the inner member also having a cylindrical opening. Openings in both members may be aligned or moved to eccentric positions upon relative rotation of the inner and outer members. Both members are held in a housing.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
150 words
For use with a tubular conduit, an assembly including a coupling comprising longitudinally aligned inner and outer members having apertures providing engaging surfaces for the conduit, the aperture in the inner member being a cylindrical, smooth, inwardly-facing surface, the members being both generally cylindrical and relatively rotatable and having interengagement regions eccentric to the axis of the members whereby the tubular conduit received into the apertures can be gripped between the members by relative rotation of the members to cause relative lateral displacement of the apertures of the respective members, at least one radially projecting retaining element on the inner member received into a recess in the outer member inhibiting relative axial movement between the members, the outer member being axially split and dowels and cooperative openings being provided in the split faces thereof to facilitate assembly; and housing means snugly and peripherally enclosing the outer member in press fit.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
33 words
A coupling according to claim 1 wherein means are provided to indicate location of the members with the apertures at positions of maximum and minimum eccentricity or at a position of radial coincidence.
