A two-part buckle for interconnecting two strap portions F of a safety belt comprises a flat plate E connectable to one strap portion and a second part having a base B with means at one end for connecting another strap portion and a lever D pivoted to the base with two latching projections, 34 at one end for engaging the plate E and having a push button 37 at the opposite end of the lever by which the latching projections S may be rocked to disengage it from the plate E, spring means 47 normally urging the lever into the latching position. The base B has an opening 14 for the adjusting end of the webbing F which passes a round or knurled bar 15 sliding in slots 17 so that under tension the webbing is clamped between the bar 15 and a stop flange 20.
