Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
129 words
A swivel coupling comprising: a first resilient portion and a second resilient portion, the first portion being solid except for a first bore provided therethrough for grippingly receiving a cylindrical elongated member, the second portion being solid except for a second bore provided therethrough for grippingly receiving an elongated member, each portion defining a slot having a width less than the diameter of its respective bore, the slot being aligned with and extending radially from its respective bore and extending to the outer surface of the respective portion, and interlocking engagement means for pivotally connecting the first portion to the second portion such that each portion is rotatable with respect to the other about an axis which is substantially perpendicular to elongated members when received in the respective bores.
Claim 2
Dependent Claim
