ABSTRACT:
A tubular assembly embodying a pin and slot connection between two thin wall tubular members having end portions disposed in telescopic relation with respect to one another. The outer tubular member having the slot also has an opening extending therethrough in closely spaced relation to its edge in a position generally alongside the slot providing an axially elongated wall portion between the opening and slot. The wall portion has a fixed integral outer end spaced axially outwardly of an intermediate locking section of the slot and a fixed integral inner end spaced axially inwardly of the intermediate locking section of the slot and is operable to resiliently deflect laterally when the pin is moved axially inwardly through the slot to thereby permit the locking section of the slot to expand in its width dimension and permit yielding passage of the pin axially thereby into received relation within the inner section of the slot.
