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.
