Patent ID: 7108289

Claim:
A pipe joint comprising a male first pipe portion, a female second pipe portion, a compression gland securable with an externally tightenable fastener to the female second pipe portion, and a restraining gasket, said gasket further comprising: a) a deformable body; and b) a locking member, at least partially embedded within the deformable body, wherein at least a portion of the locking member is positioned to engage the first pipe portion, wherein said locking member is adapted to adopt a position in which (i) the locking member bites into the first pipe portion and the second pipe portion upon compression of the gland against said gasket by the tightening of the fastener; and (ii) said locking member resists movement of said first pipe portion in a direction outward of the second pipe portion by transferring a first portion of an extractive force to said gland and transferring a second portion of such force directly to an interior surface of the second pipe portion, which said first portion and said second portion are each of a magnitude less than the magnitude of the extractive force.
