An insulating housing has therein a sealing ring having a central peripheral groove. An electrical terminal connected to an electrical lead can be inserted into the housing through a bore in a cap in the housing and through sealing. The cap can then be driven inwardly of the housing to compress the sealing ring and thus to collapse it, to cause the sealing ring to form a seal between the housing and the lead, the cap being retained in its inward position by the engagement of lugs on the cap in windows in the housing.
