Abstract
A belt buckle for vehicle safety belts has a load bearing frame and a locking mechanism thereon. A housing encloses the frame and has an insertion slot for an insert tongue acting in conjunction with the locking mechanism. To eliminate any extraneous matter that has entered into the housing through the insertion slot, a channel leads from the insertion slot through the housing and out of the housing, forming a guide for gravity assisted movement of such extraneous matter out of the housing.
