ABSTRACT A punching device includes a fixed frame adapted to support punch means in alignment with a ram. An assembly of the punch, a guide and stripping sleeve and a stripping spring is removable as a unit, and such assembly includes means by which such assembly is retained together, especially during handling away from the frame of the punching device. To this end, the sleeve has a circumferential groove in which there is a radial aperture, and a retainer member is disposed in the groove and has a portion that projects radially through the radial aperture into an elongated recess in the punch body.
