Abstract
A locking arrangement can be used for securing electric module cards between two side walls of a housing. The locking arrangement includes two side members for fixed arrangement with the respective side walls. An opening defined between the side members accommodates electric contacts of the electric module cards. A first and a second transverse member form a frame with the side members in order to lock the electric module cards within the housing. A locking mechanism is detachably connects at least one of the transverse members to at least one of the side members by means of a snap-fit.
