Threadless button apparatus includes a button portion and a retainer portion, with the two portions being secured together with a frictional engagement between a stem or shank which extends outwardly from a button and a lock cylinder in the retainer. There is an outwardly extending protuberance on the shank of the button and an inwardly extending ridge portion at the upper part of the lock cylinder in the retainer. The inwardly extending ridge portion receives the outwardly extending protuberance for frictionally securing the two portions of the button together. The outer or distal end of the shank includes a needle nosed portion which curls over in the lock cylinder of the retainer and which straightens out as the button and retainer are separated so that the two elements may be taken apart and may be reused.
