Abstract: A one-piece terminal having a contact portion (13) extending from a channel section wire connecting portion (11). Limbs (17, 17') extend toward each other from opposite axial ends of the sidewalls (15, 15') with opposed edges defining between them a wire receiving slot (26), a portion (22, 22') of each sidewall (15, 15') adjacent a limb (17, 17') being inclined inwardly of the channel as it extends away from the base (14) and towards the limb (17, 17') to provide a stiffly compliant slot (19). A panel (25) upstands from the base (14) between the sidewalls (15, 15') to provide sealant barrier and a rigid slot (26) aligned with the compliant slot (19). Extensions of the sidewalls (33, 33') are secured together by ties (34, 35).
