A molded plastic article such as a connector block for connecting signal transmission lines in a blasting system, includes a body member having a channel formed therein for receiving and retaining a mountable member, such as a detonator, and a displaceable locking member connected to the body member by one or more frangible webs which retain the displaceable locking member in a first position aligned with, but displaced from, its locking position. The mountable member, e.g., a detonator, is inserted into the channel of the connector block and a force is applied to the displaceable member to rupture the frangible web or webs and move the locking member through a passageway in the block for locking engagement with the detonator to retain the detonator therein. Flexible, cantilevered line retaining means may be disposed on the body member to receive one or a plurality of outgoing signal transmission lines. A method of assembling a mountable member within the article, is also provided. The molded plastic article may be any other suitable device, such as a tool handle in which a tool blade is secured in the same manner as the detonator is secured in the connector block. |
