Abstract
A seal of the type having a housing with internal resilient fingers for receiving a shouldered stud in locking engagement. The housing is generally cylindrical with a closed end and an open end. In one embodiment of the invention a separate member carrying the resilient fingers is secured into the open end of the housing. In another embodiment of the invention a cylindrical metallic member having an open end and a closed end is retained in the housing behind the member carrying the resilient fingers so that access to the fingers to release the stud cannot be had by cutting off the end of the plastic housing, and the fingers cannot be manipulated by the insertion of a needle or other sharp instrument through the exterior of the housing.
