A harness 10 includes a buckle 20 for releasably securing harness strap ends 13 and 14 in one of two alternative conditions. The buckle includes a frame 21 and a pivoted clasp member 37. One strap end 13 is secured to the buckle frame. The other strap end 14 may be connected through an opening 38 between the clasp member 37 and a clamping surface 26 on the frame. The clasp 37 is normally held closed by a spring 46, operating against an eccentric clamp surface 42 on the clasp member 37. Alternatively, a spring arm of the spring 46 may be lifted, and the free end of the strap end 14 may be inserted through the buckle between the clasp member 37 and the spring arm. When released against the strap, the spring arm will hold the strap for release upon application of prescribed tension along the straps. The clasp member is mounted to the frame within angular slots to permit opening of the clasp to accept thick straps or straps of double thickness.
