A pair of hole punching pliers, so-called stoma pliers, is arranged to punch a hole in a skin protection plate for a stoma bag. The hole punching remedies of the pliers consist of a hole socket (16) and a holding-up plate (18) for the same. During the punching, a plastic skin protection plate is located between the hole socket (16) and the opposing surface of the holding-up plate (18), as the free, outer cutting/punching edge (22) of the hole socket (16) after the completion of the punching abuts directly on said opposing holding-up plate surface. To achieve an optimal punching operation, which is dependant upon the hole socket's (16) outer punching edge part (22) being placed maximally perpendicularly on said holding-up plate surface, at the same time as this surface should be able to dislocate (turning eccentrically) in relation to the wearing effect of said outer punching edge part on the surface of the holding-up plate by its abutments against same at the completion of each hole punching, at least the hole socket (16) has pivotal bearing around a lateral axis (24), which is arranged perpendicularly on its symmetrical axis (26), which in its closed position at the completion of each hole punching runs eccentrically in relation to the symmetrical axis (30) of the holding-up plate (18), which said symmetrical axis forms the pivotal axis of the holding-up plate (18).
