Devices and Assemblies for Retaining Items

A retention system for releasably holding a first item within proximity to a second item, the system comprising:

• a body formed of an elastomeric material;
• wherein the body is formed with an inboard cutout for receiving the first item, which is to be retained;
• wherein the cutout elastically stretches to receive the first item and thereafter holds the first item at least in part with compression;
• and
• a tether having a first end and a second end;
• wherein the first end of the tether is coupled to the body;
• and
• a releasable coupler that is coupled at a second end of the tether, wherein the releasable coupler is for coupling to the second item.

An assembly for holding a first item proximate to a second item, the assembly comprising:

• a tether having a first end and a second end;
• wherein the tether has a longitudinal length greater than 7.5 centimeters;
• a body formed from elastomeric material;
• wherein the body has a width greater than five centimeters;
• wherein the first end of the tether is coupled to the body;
• a fastening device coupled to the second end of the tether and operable to releasably couple to objects;
• and
• wherein the body comprises an elastomer having an inboard opening that stretches to receive the first item and hold the first item in compression.
