Apparatus for retaining an electrical component such as a fuse comprises a walled, hollow body the front of which is split to form a yieldable socket for the accomodation of one end of the component and including a resilient arm extending from the rear wall to form a loop having a portion thereof lying between the front and rear walls in a position to engage the end of the component. The arm terminates in a free end which bears against the rear wall of the body. Retainers constructed according to the invention are adapted to be used in pairs and may be mounted in an insulated carrier block having resilient latch fingers which project into openings formed in the rear wall of each retainer. The retainer bodies may be used either in pairs or in gangs of pairs. When the bodies are ganged, each body is connected to a common conductor incorporating means for connecting it to an electrical circuit.
