ABSTRACT OF THE DISCLOSURE A self-locking hinge for interconnecting two structural elements such as sections of tent poles includes a pair of bifurcated lugs in opposed end-to-end relationship and a yoke extending between the arms of the lugs. A pin extends through the arms of each lug and a slot or slots in the yoke for pivotally connecting the lugs to the yoke. The pins are biased towards each other by a spring in the slot or by springs in the slots, so that projections on the arms of one lug are biased into grooves in the arms on the other lug to lock the hinge in an open position. In order to close the hinge, the lugs are pulled slightly apart against the action of the spring(s) to remove the protections from the grooves, permitting rotation of the lugs relative to the yoke and to each other.
