Abstract:
A pre-assembled pipe coupling (11) includes a gasket (200), a housing (12) surrounding the gasket, and a fastener (20). The housing has three segments sequentially coupled to each other to define an insertion boundary. A first segment (12c) includes a first mount (18) extending lateral in a first direction from the wall and having a plurality of first lateral walls that define a first aperture (22), and a second mount (18) extending laterally in a second direction from the wall, the second mount having a plurality of second lateral walls that define a second aperture (22). A second segment (12a) includes a first hook (14) disposed in the first aperture and a first tab (16) defining a first fastener aperture. A third segment (12b) includes a second hook (14) disposed in the second aperture and a second tab (16) defining a second fastener aperture. The fastener is disposed through the first fastener aperture and the second fastener aperture.
