Abstract:
1. Apparatus for retaining concentric parts within one another and enabling limited axial movement therebetween, said apparatus comprising: an inner component having a shoulder disposed on an external perimeter thereof; an outer tubular component having a wall, an open end for receiving said inner component and an inner surface for abutting the shoulder and enabling a sliding interface therebetween; a retaining tab disposed in the wall proximate the open end, the tab having one end attached to the wall, a free end and a body disposed parallel to a longitudinal axis of the outer component, said tab having suitable thickness for enabling depression of said free end toward the wall; and a slot formed in the wall beneath the tab, said slot having an end sized and disposed for enabling said free end to be forced therepast, by depression of the tab, in order to retain said free end inside the wall for engagement with said shoulder thus preventing separation of said inner component from said outer tubular component.
