Two shot tube retention fastener with anti material peeling feature
First Claim
1. A tube retention fastener, comprising:
- a body of a polymeric first material, the body including;
first and second walls;
a semi-circular sleeve defining a longitudinal cavity between the walls; and
first and second deflecting wings connected to the first and second walls respectively and directed toward a longitudinal axis of the longitudinal cavity in a non-deflected condition;
an isolation member of an elastically resilient second material including;
a first portion fixed to the semi-circular sleeve;
wherein the first portion comprises first and second contact end fixed to the first and second deflecting wings respectively; and
first and second free extending portions each positioned between and freely extending between the first portion and one of the first and second contact ends; and
each of the first and second deflecting wings includes first and second teeth to increase a surface area of the first and second deflecting wings in contact with the first and second contact ends.

Abstract
A tube retention fastener includes a polymeric material body having first and second walls and a semi-circular sleeve defining a longitudinal cavity. First and second deflecting wings individually connected to one of the first or second walls are directed toward a longitudinal axis of the longitudinal cavity in a non-deflected condition. An elastically resilient material isolation member includes a first portion fixed to the semi-circular sleeve, and first and second contact ends fixed to the first and second deflecting wings. Isolation member free extending portions are positioned and freely extend between the first portion and the contact ends. First and second wing receiving cavities are created between the deflecting wings and the first and second walls in the non-deflected condition. The deflecting wings, the contact ends and the free extending portions elastically deflect into one of the wing receiving cavities when a tube is positioned between the deflecting wings.

9. A tube retention fastener, comprising:
-
a body of a polymeric first material, the body including; first and second walls; a semi-circular sleeve defining a longitudinal cavity between the walls; first and second deflecting wings connected to the first and second walls respectively, each having a free end directed toward a longitudinal axis of the longitudinal cavity in a non-deflected condition, each free end including first and second teeth; and an isolation member of an elastically resilient second material having; a first portion fixed to the semi-circular sleeve; a plurality of longitudinal resilient ribs directed toward the longitudinal axis of the longitudinal cavity and located only in the first portion; and first and second free extending portions each freely extending from the first portion and fixed to the first and second teeth of the free end of the first and second deflecting wings respectively, and positioned such that a tube entering the longitudinal cavity between the first and second deflecting wings initially contacts the first and second deflecting wings before contacting the first and second free extending portions. - View Dependent Claims (10, 11, 12, 13, 14, 15)
