Two handlebars on bicycle I have butterfly shaped handlebars on my hybrid bicycle.  These were an aftermarket addition.

These allow for different positions but I would like to add another set of handlebars with a wider position above the butterfly handlebars.

There is a component that allows this attachment of additional handlebars but I do not know what it is called.  This looks like two bars with loops on each end and they are positioned on to the existing handlebars and affixed then to the additional handlebars above the existing.



Can anybody help with the name of this component and where to get them?
From later comments - those loop-type attachments are only rated for attaching accessories like lights and so-forth.

These are NOT handlebars



They are intended to be used like this



If you want higher bars, then raise your bars with a higher stem.  The dirty-hack described in JonR's excellent answer remains a workaround at best.

Always consider how you're going to get to the brakes in an emergency.
