Fitting apparatus for soft tubing

A fitting for use with soft tubing, comprising:

• (a) a nut portion defining an aperture for insertion therethrough of a tubing, said nut portion having a threaded portion;
• (b) a body portion defining a path for the flow of fluid therethrough and including an axially slideable sleevelike member projecting from a first end of said body portion, said axially slideable sleevelike member being supported in said body portion by an inwardly projecting collar portion, said axially slideable sleevelike member including means cooperating with said body portion for limiting the axial movement of said axially slideable sleevelike member between first and second axial positions, said axially slideable sleevelike member being adapted for insertion at least partially into the tubing, said body portion including a threaded portion adapted for cooperation with the threaded portion of said nut portion;
• and
• (c) said nut portion having a radially inwardly projecting collar portion for engaging the outer surface of the tubing, said collar portion of said nut portion cooperating with said axially slideable sleevelike member to retain the tubing in the fitting when a tensile pull is exerted on the tubing.

A fitting for use with soft tubing, comprising:

• (a) a nut portion defining an aperture for insertion therethrough of a tubing;
• (b) a body portion defining a path for the flow of fluid therethrough and adapted for releaseable connection to said nut portion, said body portion including axially slideable means interconnected to said body portion so as to be integral therewith, said axially slideable means being supported by said body portion for axial movement and further including means cooperating with said body portion to limit axial movement of said axially slideable means between first and second positions, said axially slideable means being adapted for at least partial insertion into the tubing;
• and
• (c) said nut portion including an inner surface portion cooperating with said axially slideable means to retain the tubing in the fitting.
