A button has a body and a retainer for securing the body to cloth. The retainer has a T-shaped member with the leg of the T-shaped member remote from the cross piece shaped to form a hollow cup-shaped resiliently expandable member, the rim of which is directed toward the cross piece. The body has a receptacle formed by a blind bore opening into a cup-shaped cross section similar to that of the resiliently expandable member. In operation the resiliently expandable member rim is contracted and the resiliently expandable member is pushed through the bore into the receptacle cup-shaped cross section whereupon the resiliently expandable member expands to hold the retainer in locked position with the body. |
