A push button is provided which is adaptable for pressing onto a stud having redges extending radially therefrom. The push button is provided with at least one resilient finger protruding from the wall of a blind hole formed in the shank of the button. The resilient finger is angularly disposed toward the center of the blind hole such that the end face of the finger is disposed behind a ridge with the push button positioned on a stud. The push button is provided with an opening for each resilient finger, which opening extends from outside the button towards the locality of the end face of the resilient finger and is of a dimension to eclipse, or cover the cross-section of the resilient finger when projected onto the plane of the opening.
