Abstract: An apparatus for restraining a member includes a gland, a plurality of bolts disposed in the gland, a plurality of wedges disposed in the gland, a “C” shaped clip, and a spacer. The gland has pockets and a face having an access opening providing lateral access to each pocket. Each gland pocket includes a wedge having teeth and a cavity. Each cavity includes a slot formed transverse to the bore. The clip is sized to slide through the access opening of the gland and shaped to be closely received in the slot of the wedge. The spacer attaches to the bold and has flexible prongs.

Abstract: A novel gasket includes at least one gripping element embedded in an annular member for forming a seal between two tubulars. For tubulars having socket and spigot ends, the gripping element includes teeth for gripping an outer surface of the spigot end and a blunt tooth for contacting a front wall of the socket end. The blunt tooth rolls along the front wall during relative movement between the tubulars and can include a contacting face of a specialized geometry to adjust contact dynamics and/or roughened surfaces to increase the frictional contact between the blunt tooth and the front wall. The embedded element can also include at least four teeth arranged such that no more than two teeth normally grip the outer surface of the spigot end. One or more teeth can also include a transverse groove to enhance penetration into the outer surface of the spigot end.
