A protective case in two parts (L, R) interconnected by a flexible top wall (28) acting as a hinge and a closure spring. Opposed jaws (32, 34) in the two respective parts (L, R) hold a stethoscope chestpiece (40) within the case, and protect its diaphragm (43) behind a separable (24) front wall (22). The jaws have insertion ramps (33A, 35A) that open the jaws upon insertion of the chestpiece, a retention portion (33C, 35C), and removal ramps (33D, 35D) that open the jaws upon removal. A chest piece is inserted by pushing it into the insertion ramps. It is removed by pulling it outward against the removal ramps. This protects the chestpiece from damage in a medical equipment bag to which the case may be attached by a lanyard (37) for quick location. A back wall (23) may protect a second diaphragm (45) of the chestpiece.
