ABSTRACT:
A tent is supported by outwardly leaning pairs of arches and an interconnecting flexible ridge member having a special fitting at each end. The ridge member is associated with the outer cover by positioning in a tunnel formed in the outer cover, so that the outer cover may be tensioned to form the shelter. The special fitting may be positioned in a grommet in the outer cover at one end while the identical special fitting at the other end may be used for tensioning.
