Retaining device

A retaining device comprising:

• a retention channel adapted to receive an element for retention within the channel;
• and
• an over-centre latch actuable to retain the element in the retention channel,
• wherein the retention channel comprises;
• a sprung arm, having a first inner channel wall;
• and
• a channel arm, having a second inner channel wall;
• wherein the first and second inner channel walls form a clamping surface within the retention channel, and wherein a sprung arm is displaceable between an open position to admit the element for clamping and a closed position to clamp the element with the clamping surface, by actuation of the over-centre latch;
• and
• wherein the over-centre latch comprises:
• a lever mechanism including:
• a lever arm;
• and
• a rotable linkage element,
• said lever mechanism configured to actuate the retention channel between an open position and a closed position;
• and
• wherein actuation of the lever mechanism to the closed position displaces the sprung arm from the open position to the closed position and applies a constrictive force upon the element to retain the element with the clamping surface.
