A molded plastic article such as a connector block (10) for connecting signal transmission lines in a blasting system, includes a body member (12) having a channel (18) formed therein for receiving and retaining a mountable member, such as a detonator (20), and a displaceable locking member (28) connected to the body member by one or more frangible webs which retain the displaceable locking member (28) in a first position aligned with, but displaced from, its locking position. The mountable member, e.g., a detonator (20), is inserted into the channel (18) of the connector block (10) and a force is applied to the displaceable member to rupture the frangible web or webs and move the locking member (28) through a passageway in the block (10) for locking engagement with the detonator (20) to retain the detonator (20) therein. Flexible, cantilevered line retaining means may be disposed on the body member (12) to receive one or a plurality of outgoing signal transmission lines (45).
