A restrained pipe coupling includes a restraining gland assembly having an annular main body with multiple gripper units movably connected to the annular main body. Each gripper unit includes a gripper housing having a bottom sliding surface, a gripper bolt fixedly secured to the gripper housing and radially movable through a gripper opening in the annular main body and fixable at different positions, and a gripper body having a top sliding surface and a bottom gripping surface. The sliding surfaces of the gripper housing and the gripper body are in slidable contact and angled between 20 and 30 degrees from the axial direction of the annular main body.

A fluid line support system includes a fluid line and a collet having an insertion end and a thickened portion having a biased end. A fluid valve has a valve aperture that receives the insertion end of the collet. A collet securing device has a fluid line portion that engages the wall of the fluid line, wherein at least the fluid line portion encircles the wall and is slidably engaged with the wall to define a loose position and a securing position. A collet portion of the collet securing device engages the retaining portion of the fluid valve when in the securing position. When in the securing position, the fluid line portion engages the biased end of the collet, wherein the fluid line and collet portions bias the retaining portion and biased end toward one another such that the insertion end is positioned at a final insertion depth.

A pipe coupling includes two or more partially annular clamp housings, each of which includes two opposing clamp members and one or more tightening elements for tightening the clamp members towards each other in a direction transverse to an axial length of the annular clamp housings. An elastomeric seal assembly is located in seal housings at opposite axial ends of a cylindrical shell. Tightening the clamp members towards each other causes the elastomeric seal assembly to apply a radially-inward clamping force on a pipe or pipes clamped by the pipe coupling. Radial force grippers are spaced about a circumference of each of the annular clamp housings. Radially-inward forces of the radial force grippers create axially-directed forces on the pipe or pipes clamped by the pipe coupling.

A reusable clamp for retaining conduit sections or sanitary fittings having circular flanges together includes two gland members movable between open and closed positions. The gland members include two handles projecting outwardly from the gland members and two sets of locking detents formed on a latch finger connected to one gland member and the outer periphery of the other gland member. The locking detents engage to prevent movement of the gland members away from the closed position until a latch release arm coupled to the latch finger is depressed towards one of the handles, which causes the locking detents to disengage from one another and enables re-opening of the clamp when desired. The latch release arm and one or more of the handles also include tie-receiving loops to prevent accidental opening of the clamp unless desired by the end user.

The present invention relates to a compact connector design with an internal locking ring (11). The connector according to the invention comprises a locking ring (11) allowing bayonet type connection on either side with two riser sections. Furthermore, the connector comprises at least one removable pin (12) for translationally blocking locking ring (11), notably upon locking and unlocking.
