ABSTRACT:
A strain relief device for resisting strain forces acting in a direction of pull-out of a cable relative to a cable closure, comprises a cable gripping member having at least two complementary jaw-like segments alignable for defining therebetween a tubular through opening sized for gripping a cable of a given diameter therewithin and an outer surface of predetermined configuration. These jaw-like segments have interengageable edge surfaces for defining a maximum inwardly compressed condition of the through opening corresponding to a predetermined limited maximum compression of the given diameter of cable for substantially preventing damage thereto. A generally annular locking member comprises a pair of locking segments defining an inner surface formed for complementary surrounding engagement with the gripping member outer surface and coupling structure for releasably coupling the locking segments together about the gripping member to retain the same in gripping engagement with the cable.
