Abstract: A coupling for joining (10) pipe elements has segments surrounding a central space with cusps which engage lobes of a seal to maintain the segments in spaced apart relation in a preassembled state. While the coupling is in the preassembled state the pipe elements (64) , (66) may be inserted into the central space without disassembling the coupling, and portions of the seal adjacent to attachment members on the segments seat within a channel defined by the segments between the cusps. When the seal is compressed between the segments and the pipe elements to form a joint the seal deforms so as to withdraw a center leg (38) of the seal from the flow path defined within the pipe elements (64) , (66).
