Lock-claw for pneumatic quick-connect fitting

Abstract

A lock-claw (1) for pneumatic quick-connect fitting is provided, comprising an annular crown (2) developing around a central axis (2a) on a main plane (2b) orthogonal to the central axis (2a); and a coupling portion (3) protruding from the annular crown (2a) radially to the central axis (2a) towards the central axis (2a) and developing along a humped development surface secant to the main plane (2b) so as to define a first humped zone (30) proximal to the annular crown (2) and a second flexible zone (31) separated from the annular crown (2) by the first zone (30); wherein the coupling portion (3) is divided into a plurality of tabs (4) distributed around the central axis (2) and mutually separated by inlets (5) extending radially to the central axis (2a) over part of the first zone (30) and the entirety of the second zone (31); and wherein each tab (4) is perforated by defining at least one slot (40).

Dependencies are inferred from the claim text.
