Abstract: The receptacle (2), which is especially for mating with a ceramic chip resistor (4), comprises first and second superposed plates (6 and 8) defining a tapered passage (12). The plates are joined by resilient bights (14) on opposite sides of a mouth (10) of the passage (12). The first plate (6) is connected to the bights (14) at positions (P) spaced back from the mouth (10) so that a portion (15) of the first plate (6) projects freely between the bights (14). The resistor (4), when inserted into the passage (12) by way of the mouth (10), tilts the first plate (6) about its connections with the bights (14) so that the resistor (4) is tightly gripped between the plates (6 and 8) when the leading end (37) of the resistor (4) reaches a stop (28) beyond the positions (P) at which the first plate (6) is joined to the bights (14).
