Three-piece device ear hook

A method of assembling an ear hook, comprising:

• passing a retention sleeve in a first direction beyond an end of one of a device hook engagement component or an ear hook engagement component by at least a predetermined distance;
• inserting another of the device hook engagement component or the ear hook engagement component into a bore of the one of the device hook engagement component or the ear hook engagement component;
• and
• moving the retention sleeve in a second direction toward the end to pass a protuberance of the retention sleeve over a cantilevered protuberance engagement component to retain the one of the device hook engagement component or the ear hook engagement component together as an assembly.

An assembly, comprising:

• a device hook engagement component;
• an ear hook engagement component;
• and
• a retention sleeve comprising at least one protuberance extending into the retention sleeve toward an engagement axis of the assembly;
• one of the device hook engagement component or the ear hook engagement component comprising:
• at least two retention sleeve friction engagement components radially separated by a cantilevered protuberance engagement component about the engagement axis;
• the cantilevered protuberance engagement component comprising a distal end biased against the at least one protuberance to retain the device hook engagement component and the ear hook engagement component together,
• the one of the device hook engagement component or the ear hook engagement component defining a gap adjacent to the cantilevered protuberance engagement component opposite the distal end.

An assembly, comprising:

• a device hook engagement component;
• an ear hook engagement component;
• and
• a retention sleeve comprising at least one protuberance extending into the retention sleeve toward an engagement axis of the assembly;
• one of the device hook engagement component or the ear hook engagement component comprising:
• at least two retention sleeve friction engagement components radially separated by a cantilevered protuberance engagement component about the engagement axis;
• the cantilevered protuberance engagement component comprising a distal end biased against the at least one protuberance to retain the device hook engagement component and the ear hook engagement component together;
• and
• a hook extending distally from the device hook engagement component and an ear hook extending distally from the ear hook engagement component.

An assembly, comprising:

• a device hook engagement component;
• an ear hook engagement component;
• and
• a retention sleeve comprising at least one protuberance extending into the retention sleeve toward an engagement axis of the assembly;
• one of the device hook engagement component or the ear hook engagement component comprising:
• at least two retention sleeve friction engagement components radially separated by a cantilevered protuberance engagement component about the engagement axis;
• the cantilevered protuberance engagement component comprising a distal end biased against the at least one protuberance to retain the device hook engagement component and the ear hook engagement component together;
• the at least two retention sleeve friction engagement components further radially separated by a protuberance passage channel.
