Twist-locking coupler system

Abstract

A twist-locking coupler system includes a locking hub and a first and a second tubular element. The locking hub includes a central portion having a first side and a second side. A first coupling element extends in a first direction from the first side of the central portion. A second coupling element extends in a second direction from the second side of the central portion. The second direction is opposite the first direction. The locking hub includes a tab-in-groove locking element on a first surface of the first coupling element and a tab-in-groove locking element on a first surface of the second coupling element. The first and second tubular element each receive, respectively, the first and the second coupling element in an overlapping configuration. The rotation of the locking hub about a longitudinal axis of the first and second tubular elements slides the tab-in-groove locking elements of the first and second coupling elements adjacent corresponding tab-in-groove locking elements on the first and second tubular elements, thereby coupling the locking hub to both the first and second tubular elements.
