ABSTRACT:
A fastener system for joining together the nested ends of first and second generally tubular housing members in a tight-fitting, leak-proof manner by the use of at least one tightly compressed O-ring. The first housing member has at one end a reduced diameter external portion of finite length, around which an encircling external groove is located, whereas the second housing member has an interior portion sized so as to be able to closely receive the reduced diameter external portion of the first housing member. An encircling groove is formed around a portion of the interior of the second housing member, whereby upon the joinder portions of the first and second housing members being tightly interfitted, the encircling grooves will be brought into substantial alignment, to define an annular cavity of a size larger than either of the encircling grooves individually, into which cavity an elongate locking strip or splice ring can be readily inserted for a substantial distance, to lock the members tightly together. An O-ring may be disposed in the innermost portion of either or both of the housing members, and positioned such that the extreme end of the other housing member can come into direct therewith, thereby to achieve a sealed, leakproof joinder of the first and second housing members at such time as the joinder portions of the two housing members are brought tightly together and the locking strip inserted.
