STETHOSCOPE

摘要

A stethoscope is provided having ear tubes connected by a resilient band which permits swinging movement of the free ends of the ear tubes toward and away from each other in a plane for insertion for use and removal but resists displacement of the ear tubes from that plane, the ends of the resilient band being formed into spring collars and having struck out projections engaged in slots in the tubes to prevent longitudinal separation and turning of the tubes.
