The Houdini stop chest strap is a safety device which prevents your child from taking their arms out of their harnessing. The Houdini strap consists of two clips joined by a length of material. The clips simply connect over the existing harness straps and hold them firmly in position, preventing your child from wriggling out.
A Houdini lock is the latest revolution and a real must for a busy mums nappy bag. The Houdini locks are amazing and have many uses and have even been described as the swiss army mum's device.
