Abstract
Abstract A telescoping-type connector comprising outer and inner telescoping members, the inner telescoping member defining an outer circumferential groove, and adapted to sealingly fit in telescoping relation within an aperture of the outer telescoping member. The outer telescoping member includes retention means for releasably projecting into the outer circumferential groove, to retain the inner and outer members in the desired sealing, telescoping relation. In accordance with this invention, the inner telescoping member defines, between the circumferential groove and the forward end of the inner member relative to the outer member, a recessed portion on its outer surface for facilitating molding and the like. Ribbed members are positioned within the recessed portion, to prevent the retention means from projecting therein and providing inadequate locking of the connector.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
162 words
In a telescoping-type connector comprising outer and inner telescoping members, said inner telescoping member defining an outer circumferential groove and adapted to sealingly fit in telescoping relation within an aperture of the said outer telescoping member, said outer telescoping member including retention means for releasably projecting a plurality of spaced retaining members into said outer circumferential groove to retain said inner and outer members in said sealing, telescoping relation, the improvement comprising, in combination: said inner telescoping member defining, between said circumferential grooves and the forward end of said inner member relative to said outer member, a recessed portion on its outer surface, and a plurality of circumferentially spaced, longitudinally extending rib members positioned within said recessed portion, said rib members being disposed in a position to prevent at least one of the retention members of the retention means from being projected into said recessed portion in any rotational position of said inner telescoping member while positioned within the outer telescoping member.
Claim 2
Dependent Claim
