A clamp device with resilience can be coupled to a slender bar. The slender bar includes a connection rod and a bar shaft which are connected to each other. The clamp device with resilience includes a clamping portion and a fixing portion. The clamping portion includes two clamping plates for containing the connection rod. The fixing portion is connected to the clamping portion and adapted to fix the bar shaft in place. Rotation of the connection rod causes the two clamping plates to abut against polygonal vertices of the connection rod and therefore move away from each other. Therefore, the connection rod rotates by a fixed angle on each instance.

A coupling element (10) for the connection between a first grilled wall (P) and a second grilled wall (P) adjacent and orthogonal to each other of a pet cage, comprising an elongated body (11) one side of which ends with an arched coupling appendage (12), and the opposite side with a head (13) comprising two further arched coupling appendages (15, 16) facing opposite sides of the body (11). Said arched appendages (12, 15, 16) define a first seat (14) and a second seat (18) for the coupling to two rods f1, T) forming part of the first grilled wall (P) and a third seat (18) for coupling to a third rod (T) forming part of the second grilled wall (P) to which the first wall (P) is connected. The third seat (18) is associated with an elastic tongue (19) adapted to contrastingly retain said third rod (T) of said second wall (P) to which the first wall (P) is connected.
