摘要： A key is receivable in a T-groove of a support for securing an object to the latter. The key has an elongated body provided with two spaced parallel end faces extending transversely to the longitudinal axis of the body, a pair of side faces each of which includes a first side face portion extending longitudinally of the body from one of the end faces part of the distance towards the other end face, and a second side face portion extending from the respective first side face portion to the other end face. The first side face portions extend parallel to the longitudinal axis and are transversely spaced by a distance smaller than the narrowest dimension of a T-groove into which the body is to be inserted, and the second side face portions are inclined from the respective first side portions in direction towards the longitudinal axis. An upper face of the body has in the region of the end faces respective upper face portions which are located at opposite sides of the longitudinal axis and which are adapted to engage from below the respective opposite shoulders bounding the narrowest dimension of the T-groove. A screw or similar arresting device is provided for arresting the body in the T-groove.
