Abstract: An apparatus for ensuring the proper existence and location of wire harness retainers along the length of a wire harness is provided. The apparatus is adapted to receive a wire harness retainer and, once the retainer is inserted, to generate a signal indicating the retainer has been inserted.

Abstract: A bitting rig apparatus (10) for training horses is disclosed. A preferred embodiment of the bitting rig apparatus (10) includes an elongated, flexible member (12), the member (12) being releasably attached at its ends to a saddle (14) on a horse on opposite sides of the horse. A ring-like member (18) is slideably positioned on the elongated member (12) for slideable movement therealong. A second elongated member (20) extends through the ring-like member, the ends of the second member (20) being releasably attached to shanks (24) at opposite ends of a bit (26) positioned in the horse's mouth.

Abstract: A releasable latching mechanism for a checkrein having a body fixed to a harness and in which is removably accommodated an anchor secured at one end to a checkrein. Locking balls are accommodated in openings formed in a wall of the body, the balls being of larger diameter than the thickness of the body wall. An operating sleeve is mounted on the body for sliding movements between positions in which the anchor member is latched and released. When the operating sleeve is in its anchor latching position the inner surface of the sleeve bears against the locking balls and forces them inwardly of the body so that portions of such balls project into an annular groove formed in the anchor member, thereby preventing separation of the anchor member from the body.
