Abstract

A first shot body member includes a pair of side walls, a semi-circular sleeve positioned between the pair of side walls to define a portion of a longitudinal pocket, and a pair of deflecting wings. Each deflecting wing is coupled to one of the side walls at a corner. A second shot isolation member of an elastically resilient second material is bonded to portions of an interior surface of the longitudinal pocket defined by each of: the semi-circular sleeve, each of the pair of side walls, each of the pair of corners, and each of the pair of wings. Mold members can include supporting surfaces to support interior and exterior portions of the wing during the second shot molding operation, while leaving an exposed interior bonding surface that defines a portion of the second shot molding cavity. Related methods are further disclosed.

5. The tube retention fastener of claim 1, wherein a longitudinal end face of the isolation member is interiorly offset from a longitudinal end face of the body adjacent an entire longitudinal pocket length from the first corner along the first side wall, the semi-circular sleeve, and the second side wall to the second corner.

6. The tube retention fastener of claim 1, wherein the resilient member further comprises a plurality of longitudinal ribs within the longitudinal pocket, and wherein a pair of opposing longitudinal ribs define an entry throat that is narrower than a diameter defined by the plurality of longitudinal ribs.

7. The tube retention fastener of claim 6, wherein each of the pair of deflecting wings has a deflected position in which a distance between outer surfaces of each of the deflecting wings is larger than the entry throat.

8. The tube retention fastener of claim 1, wherein the distal end of each deflecting wing has a disruptive shape with the isolation member bonded thereto.
